I prefer Pacific Rift over Apocalypse. I just like the environments from pacific rift better. I want the new Motorstorm, however I'm not willing to drop 20 on it.
Apocolype was not fun. It was just a spectacle of a game with way to much crap going on that killed the actual racing. Pacific rift is one of my top 3 or 4 racers of all time. I wouldnt pay 10 for apoc.... its just not fun to play.
