It's kinda hard for fps games to really be innovative without breaking the game or making it no longer feel like an fps. It's become pretty common for games to barrow ideas from each other too. If its different enough though, their own spin on it, it's usually a good thing. Like technology. Destiny is a new franchise, that's much more ambitious[spoiler]also not claiming to be a straight fps game[/spoiler], however the mechanics like aim and shoot are pretty much a copy and paste from call of duty though. [spoiler]ADS is what I'm referring to, how both games have the same penalties and bonuses, like movement penalty hipfire accuracy penalty jumping causing accuracy to fall, crit damage on head shots, needing perks to bypass penalties etc. [/spoiler] Edit - neither of these games are my cup of tea, but I have tried both. One to play with a friend since its his main game, the other from being excited about its concepts, though I unfortunatley became dissatisfied and dissapointed.
