Halo Reach is utter garbage compared to the first 3 games.
I actually liked Halo: Reach, oddly enough. But to each their own.
However, Halo 4 was even worse. It's story was garbage. Armor design was garbage.
IMO, worst in the series. I guess it makes sense, since it was made by a new company, but whatever.
I mean hell:
*SPOILER*
That whole love story between John and Cortana was so bullstuff and cringe-worthy that I actually don't want to buy any more Halo games, the only probable exception being the Master Chief Collection.*END SPOILER*
I thought AC: Black Flag was boring, IMO.
Lastly, Civilization: Revolutions was so over-simplified that it's utter garbage.
