I don't own a single Sega game so I can't really comment.. but I think AvP, Bayonetta and Madworld are all pretty bad.. Valkyria Chronicles and Yakuza are decent though.. but still overrated..
Currently playing: MAG, Heavy Rain, Infamous
Getting Plat trophies for: Heavy Rain, Infamous, RE5, Burnout and GOW collection once I get it.
