Well, since waiting for entry number 300 would leave me way deeper into the next gen, I'll do this now. The worst games I've played this generation. Truth be told, I handpick my games, so most of the time I get good games. Most of the time.
Number 10) Metroid: Other M
Number 9) Bionic Commando
Number 8) Rayman Raving Rabbids
Number 7) Teenage Mutant Ninja Turtles Smash-Up
Number 6) G.I. Joe: The Rise of Cobra
Number 5) SBK: Snowboard Kids
Number 4) Cartoon Network Punch Time Explosions XL
Number 3) Lunar Dragon Song
Number 2) Harvey Birdman: Attorney at Law
Number 1) Windy X Windam
And despite all that, I still bought it. I had a bit of hope that playing it on a DS would make it better. Maybe the emulator was skipping frames or something. It wasn't. This game is the Dragon Ball Z Taiketsu of the last generation, it's so bad... it's terrible and should be avoided by everyone.
