I am a halo gamer, REACH bit of a let down wth some of the weapons, and as for that armer lock realy that just ruins the game, but still a good game, wish just made H3 more sexy, i just start to play Blc Ops never played any of the other ones, so far realy enjoying Blc Ops, my verdict is both awsome games but REACH noob friendly Blc Ops i can see you getting bored of it after time
