Which Expansion
Smash Up · Expansion

Big in Japan

Depends on your group

Our take
BGG's fan geeklist rates it second of 14 (7.5), but Assorted Meeples warns its mechanics work less well with factions from other sets.
What you need first
Playable alone for 2 players (each player mixes 2 factions); 3-4 players need a second Smash Up set or the base game. Mixes with any other Smash Up set.
What it adds
Four factions (Kaiju, Magical Girls, Mega Troopers, Itty Critters) and 8 bases, introducing oversized Kaiju cards and the optional Titans rule.
What it fixes
Brings the most-requested Japanese pop culture themes to the table.
