>>716276907 (OP)By what metric?
CSGO dominated 2010s shooters and pioneered microtransaction maxxing for games thus deserves a shot at being the decade defining game
Minecraft dominated the whole gaming scene and spawned infinite copies of survival crafting, billions of people will think of it when they hear 2010 gaming
RDR2/GTA 5 is what a lot of people will think of when they think of games that pushed the envelope of graphiv fidelity
DS is on my personal top list but I wouldn't call it game of the decade
