Consolified:
Simplified enough for a console, though not always their fault. Or have the feel of a halfhearted port to the PC from console.
Either: Overlapping key assignments, for example tap for
one thing, hold for another (DX:HR knock out/kill), or different effects in different situations (run/cover mass effect, or free run/jump
assassins creed). Basically the controls feel cramped, and could be easily spread out on the keyboard/(8 button)mouse.
OR: Interface optimised for console, then ported to PC (eg: Deus Ex: Human revolutions - hacking, witcher 2 abilities,
assassins creed select menu... etc etc etc). Alternatively crippled graphics for the PC, so consoles can run it too.
OR: The game just feels dumbed down, so that it would work with consoles not having a mouse (eg: Deus Ex:
invisible war - 'simplified' inventory), or even more frustrating, not being able to select stuff on an interface with a mouse, but rather having to go through an awkward series of up down left and rights.
OR: Finally, and it has to be said: story modified for a 'console' audience.
