I like the Dark Messiah of Might & Magic combat style, yes it's an FPS/RPG hybrid game but:
- just bashing your mouse button results in flurry, fast but powerless attacks
- stronger attacks need a powerup time (holding a button for 2 seconds)
- You need to block attacks your self
- special moves need you to perform extra actions, running, crouching...
The basic idea was there but the game couldn't convince me.
It didn't feel natural at all (this is my personal opinion)
But then again I only played the demo (I didn't buy the game because I didn't like the demo at all)
