Board Game Expansions: When to Buy, When to Skip

Board game expansions are a trap — not because they're bad, but because they're tempting before you need them. A shiny new expansion promises variety, content, and endless replayability. Most players, however, buy expansions for games they haven't played enough to exhaust the base game, leaving those boxes on shelves making setup harder and storage worse.

Only buy expansions after playing the base game 10+ times. The honest truth: most base games contain 20-50+ hours of content. Most players don't come close to exhausting that before buying an expansion. Instead of asking "is this expansion good?" you should be asking "have I worn out the base game yet?"

We play before we recommend. Our testing methodology outlines the full process.

When Expansions Are Worth It

You've Clicked With the Base Game After 10+ Plays

This is the only rule that matters. Once you've played frequently enough to feel patterns becoming predictable, an expansion refreshes the experience by adding fresh decisions, card combinations, or strategic paths.

The Expansion Fixes a Known Problem

Some base games have acknowledged weaknesses that expansions directly address:

• Catan: Traders & Barbarians — Adds structured scenarios that reduce the randomness frustration plaguing base Catan
• Dominion: Intrigue/Seaside — Dramatically expands the kingdom card pool, since the base game's 25 cards feel repetitive after 10 plays
• Terraforming Mars: Prelude — Accelerates the sluggish early game that's the base version's biggest criticism

Adding a Player Count You Actually Need

When your group consistently hits 5-6 players and the base game only supports 4, a player count expansion becomes essential. Be honest, though — most "5-6 player" expansions make games longer, not better.

When to Skip

You've Played the Base Game Fewer Than 5 Times

You don't need more content yet. Play what you've got.

The Expansion Adds Complexity Without Strategy

More rules, more tokens, more setup — but no meaningful new decisions. Some expansions are "more stuff" rather than "better stuff." In my experience, reading reviews that distinguish between the two saves you from buyer's remorse.

You're Buying It "For Later"

Expansions purchased in advance become setup anxiety. "Should we play with or without the expansion?" becomes a question haunting every game night. Just buy it when you need it.

Your Base Game Is Already Perfect

Certain games don't need expansions because they're already complete:

• Azul — Four standalone Azul games exist, but the original remains perfectly balanced as-is
• Codenames — Contains more word combinations than you'll ever exhaust
• Pandemic — Tight and complete out of the box. Expansions add variety but don't improve the core experience.
