I own a shadow and a tz. For a while I thought about exploring other games as I want to keep things fresh and never get married to a title. I played a Creech as I knew it was an A title. I honestly couldn't even finish one game. The whole field seems to be covered by a ramp. You can't see what the hell is going on. It was a snooze. I find most of the A titles boring. Played attack from Mars and almost fell asleep. In the end I have yet to find a game to replace my shadow. It so fast, cool toys, great balance, etc. In fact, my tz will leave before the shadow.
