First off Dynamic, I don't know what other term to use except for class based, but it'll do. Dynamic are games such as Halo: Reach, Halo 4, Call of Duty, or Battlefield. Secondly, we have Arena-style games, this is like Quake, Halo 1, 2, and 3, or Unreal. I've got to go with the Arena shooters, I like being set on the same ground as everyone else and your true skill (or rush to the weapons) will show.
