Halo 4 I played for the story, the MP was lacking and Flood was awful, why did they change how Infection was in Reach?
BF3 was great until I realized it was terribly balanced. Just another shooter where Level = Weapons = Skill.
CoD was great up until CoD5 (WaW), after that it turned to shit and garbage and has ruined the face of gaming.
I grew up with Halo and I love it's story, but I hope it's gameplay doesn't fall short.. but I'd rather it be a Single Player / Co-Op more than a big FPS Shooter competing against the two "realistic" FPS.
