OK, I have been playing tonight and I have to agree with Dreamcast. This is not a game for Snipers. This is more Arcade like. I guess if you call that "fast paced"....then OK. However, it's not very balanced. At least in the original COD you had some rather large maps. In CODMW, CODMW2 and COD-BO that has seemed to dissappear. The last two games appear to be what I call "spray and pray" shooters.
At least on Battelfield 3 (which is the best FPS out there IMO), you can have both close quarters intense battles and battles that are more strategic. Some maps are HUGE. IMO RUSH play in Battlefield 3 is the best FPS/Multiplayer experience out there bar none.
