Board Game Expansions: How to Decide Which One to Buy First

Quick answer

Buy the expansion that increases how often your group plays the base game, not the one with the most content. If a deluxe edition already bundles the expansion you want, compare that total package against buying the base game plus the add-on separately. Prioritize expansions you can teach in under five minutes and that work at your usual player count.

Expansions are the easiest way to waste money in this hobby. The box looks exciting, the new factions sound great, and then it sits on the shelf because your group never got past the base game. The opposite problem is just as common: you buy three small add-ons when one deluxe edition would have covered everything for less.

This guide gives you a decision order for choosing which board game expansion to buy first. It uses concrete trade-offs, not hype, and it applies whether you are looking at a big-box add-on or a small card pack. The goal is simple: spend once, play more.

Start with play frequency, not content volume

The strongest signal for expansion priority is how often your group already plays the base game. If a game hits the table monthly, almost any expansion will get used. If it has been six months since the last play, a new expansion will not fix that. Expansions add variety to a game you already enjoy; they rarely rescue a game your group has moved on from.

Write down your last five game nights. Which titles appeared more than once? That short list is your real expansion shortlist. Everything else is a maybe at best. This one filter prevents most bad expansion purchases.

• Count plays from the last three months, not the last three years.
• If a game has never been played with your current group, skip its expansions for now.
• A game you love solo but rarely play with others still counts if solo play is your main mode.

Check whether a deluxe edition already includes the expansion

Some games sell a deluxe edition that bundles the base game with an expansion and upgraded components. That changes the math completely. Buying the base game plus the expansion separately can cost more than the deluxe edition, and you may miss out on component upgrades that improve the play experience.

Before you buy any expansion, check the product page for a deluxe or collector version of the same game. If it exists, compare what is included. Sometimes the deluxe edition is the smarter first purchase even if you already own the base game, because selling or gifting the base copy offsets the cost.

• Look for the words deluxe, collector, or complete edition on the product page.
• Check whether the bundled expansion is the one you actually want, not a different add-on.
• If you already own the base game, factor in the resale value of your current copy.

Match the expansion to your usual player count

Expansions often change the supported player count or add factions that only work at certain counts. A two-player household should not prioritize an expansion that mainly adds content for five or six players. The reverse is also true: a big-group expansion can slow down a two-player game with unnecessary setup.

Read the player count on the expansion box and compare it to your real table. If your group is almost always three players, an expansion that shines at four or five will feel like dead weight. If you regularly host six, an expansion that adds a sixth player option is worth more than one that only deepens two-player strategy.

• Note your most common player count before you shop.
• Avoid expansions that only add content for counts you never play.
• A small expansion that fixes your exact player count beats a large one that does not.

Weigh setup and teach time against your group

Every expansion adds rules to teach and components to sort. If your group meets for two hours once a month, a heavy expansion that adds thirty minutes of setup will reduce how often the game hits the table. A lighter add-on that slots in with minimal explanation will get played more.

This is not an argument against big expansions. It is an argument for honesty about your table. Groups that play weekly and enjoy deep systems can absorb heavy expansions. Groups that rotate games constantly should favor expansions that add variety without adding overhead.

• Ask whether you can teach the expansion in five minutes or less.
• Consider storage space: a big-box expansion needs shelf room.
• If setup already feels long, choose an expansion that adds content without new systems.

Decide between a new expansion and a different game

Sometimes the right answer is no expansion at all. If you are bored with a game, an expansion may only delay the decision to move on. If you want a new experience, a different base game often costs about the same as a large expansion and gives you more novelty per dollar.

Use this test: would you rather play the expanded version of this game next week, or a completely different game? If you hesitate, put the expansion money toward something new. If you immediately picture the expanded game on the table, buy the expansion.

• Compare the expansion price to a full base game you are curious about.
• If the base game feels solved, an expansion may not fix that.
• Buying one great expansion beats buying two mediocre ones.

Decision rules for your first expansion purchase

• Rule 1: Play frequency first: Only consider expansions for games you have played at least three times in the last three months. If a game has not hit the table, an expansion will not change that. Checkpoint: if you cannot remember the last play, skip this expansion.
• Rule 2: Deluxe beats separate: If a deluxe edition exists and includes the expansion you want, compare its total price against base game plus expansion. The deluxe version often includes component upgrades that separate purchases do not. Checkpoint: read the deluxe contents list before buying the standalone expansion.
• Rule 3: Player count match: Buy the expansion that supports your most common player count. An expansion for a count you never play is shelf decoration. Checkpoint: write down your usual player count and match it to the box.
• Rule 4: Teach time under five minutes: If you cannot explain the expansion in five minutes, it will reduce how often the game gets played. Favor expansions that add variety without new systems. Checkpoint: if the rulebook is thicker than the base game's, reconsider.
• Rule 5: New game test: If you are bored with the base game, an expansion may not fix it. Compare the expansion price to a different base game you are curious about. Checkpoint: if you hesitate between expanding and moving on, move on.

Examples from the Rock Manor catalog

• Disco Heist Laundry (Deluxe): Upgrade to the Deluxe Edition for enhanced components and the Glitter Gulch expansion pack, adding new locations, crew members, and criminal schemes to keep every game fresh. If you are new to the game, the Deluxe Edition bundles the base experience with an expansion and upgraded components in one purchase, which can be cheaper than buying the base game and expansion separately.
• Disco Heist Laundry: Travel back in time to the radical 1980s where you'll put together a crew of criminals for the heist of the decade. Play a Crew member to your tableau, move about the city to avoid the cops, gather intel, and then grab the most cash when the window of opportunity opens. If you already own the base game and play it often, the Deluxe upgrade path is the expansion decision to evaluate first, because it adds the Glitter Gulch content without requiring a second full game purchase.
• Brass Empire (1st Edition): Brass Empire is a strategic Steampunk deckbuilding card game where 1-5 players battle and sabotage other companies to amass economic wealth and influence. A deckbuilder with a wide player count is a good candidate for expansions only if your group already plays it regularly; otherwise the base game offers plenty of variety on its own.
• Lawyer Up: Season 1: Lawyer Up: Season 1 includes all of the content from the first season of Lawyer Up including the Murder, Godfather, Witch Trial and Art Forgery cases. This is an example of a season box that collects multiple cases at once. If you enjoy the core system, a season set is often a better first expansion than a single small case pack because it adds more replay value per dollar.

Who should buy an expansion first

Best for

• Groups that already play the base game at least monthly and want more variety
• Players who own a base game and are considering a deluxe edition that bundles an expansion
• Solo players who want more scenarios or factions for a game they already enjoy

Not for

• Players who have not played the base game yet, or who play it rarely
• Groups looking for a completely new experience rather than more of the same
• Buyers who cannot accommodate longer setup or extra storage space

Pick the expansion that makes your most-played game hit the table more often, and check for a deluxe edition before buying separate add-ons. If you are still unsure, play the base game twice this month and see whether you want more of it. That answer will tell you more than any box description.
