I have to say that after playing rtcw and mohaa, I have to go towards Mohaa because it offers the complete package(from a single player's view). The sound, graphics and weapons are top notch in mohaa. But with multiplayer rtcw offers more options than mohaa(for the time being). Maybe 2015 can creates a better multiplayer part with an add-on or a patch.
