We've all played on such game at some point in our life. I know recently Prinny 2 Dawn Of Operation Panties, Dood had me slurring insults at my PSP screen for about 2 hours straight, before I snapped and threw it at the wall (luckily it didn't break lol...).
So yeah post about those games that turn you into some savage beast, maybe people will go and experience it themselves haha
