I still love Crysis, I loved that massive open world full of tactical possibilities, just as I did the original Far Cry, but the PC controls took considerable practice to get in the groove.
Far Cry just played like any other FPS game (on pc) to me. Crysis had this ingame weapon/gadget menu, which was one of the first games to do this, which was a getting used to thing, but i did adapt quick to it. They didnt only push graphics (game still holds up today even @ stock), they pushed AI, physics, gameplay and even controls like the ingame weapons/powers altering menu. They kinda had to, you needed to be able to cloack, armor or speed changes mid-game.
But a mess, nah, wouldnt call the controls to be that Also, many played at unstable framerates, which made the controls jerky.
