Of all the games to go back to you choose Burn zombie burn?
Ya know, it wasn't quite as bad as I remember it being. It's still kinda dumb though. The structure just kinda doesn't work. Having to start zombies on fire for a multiplier is dumb. Also weapons run out of ammo too quickly.
Also completely ridiculous that there are trophies on the PSN servers for DLC that was never released. I'm not a completionist or anything but damn that is dumb.
But you'll notice I went back to some better games too. Eat Them! was great. I played the Strongbad games with a guide just to experience the story/laughs and get through them. Under Siege has been fully patched with proper PS3 controls and a reasonable difficulty level, it was mildly enjoyable as well.
Super Stacker is still terrible, and the trophies are even worse. Tank Battles lost its appeal pretty quick (that one was only a buck at least.) TV Show King is ok for a quiz game but better when you're not playing the amazingly brilliant AI.
