So why dont you steer your car with a fucking keyboard? Precision in movement is not a gimmick, its fucking mandatory on a heavily movement based twitch combat system. Millions of people get along with it, millions of people enjoy it. Youre not one of them appearently because youre either not used to gamepads or your Wurstfingers are not made for action games but thats not a shortage of the game but one of your hand-eye coordination.
Azarkon:
There are plenty of rpgs with preset characters. Gothic for example or Anachronox or heck even Planescape Torment... you would say all of them are no proper rpgs? Sure you can shape their abilities to your liking but so can you in the TW3...
Rpgs are not just about complete freedom of your character development, its also about shaping the narrative based on decisions you make as an ingame character, as in having actual choice and consequence. Actually this is even (atleast for me) the most important aspect of an rpg as it draws on the very essence of its predecessor, the pnp rpg-systems.
Playing rpgs is basically about making decisions and then having the gameworld react to those decisions. Those can either be choosing a race or choosing to kill or not to kill off a certain character. If game A reacts to you killing off that character in a more fleshed out way than game B does to you choosing a certain race then theres actually more "roleplaying" going on in game A.
Decisions mean shit if they have no actual outcome.
