Personally I think gow2 was the best. Yes it had COUNTLESS problems and shitty MM, but it felt more like a memorable game to me, probably because I spent more time on it than any other game this generation and was able to get 4 extra instead of 3 friends for a team lol. Gow1 is the nostalgia game for me, countless hours of 5 round execution, friendly fire, weapon swaps, player matches, ranked was a bit bleh for me but okay occasionally. I went full on lone wolf in that game, never used my mic because I lost it lmao.
Gears 3 was overall the most polished game which is good but the multiplayer in gears has always been a diamond in the rough and in this game the cleaned the diamond and then gave it to us, which there is nothing wrong with but it feels strange sometimes. Still it's a great game none the less.
I just wish Epic will do a current gen remake of gow1 on both systems (read somewhere that epic has the rights and not Microsoft). Then both xbox and ps3 fanboys can see just how great the game was.
PS, yes on phone.
