My first Crysis game was Crysis 2 followed by Crysis on Xbox. I intend to play Crysis 3 but don't have the hardware to handle Warhead. Obviously I haven't played Power Struggle and rather than google like a lazy bum I'd rather get a discussion going in the official Crysis community.

Domination game where you control objectives/resources to manufacture a huge-ass tankcannonthingamajig to destroy the enemy base and profit greatly.

Massive maps, vehicles, objectives and a moderate amount of players (relative to the map size) to keep a high but spaced fighting volume.
