Mirrors edge is actually their BEST game! And my opinion is much more important than yours. Really.
The worst is definately Red Alert 3, mostly because I like the old cutscenes in Tiberian Sun and Red Alert 2 and the ones in RA3 are absolute 100% complete utter shittiness in a box made out of tits and more shit.
And the gameplay is the same as any other EA strategy title. Get biggest unit. Get more biggest unit. Maybe a commando unit. Win game.
