Bought this one via catalog, at first I didn't like it as much as Shift, but now that I have played it longer I like it as much if not more than the original. I am still getting used to the upgrade/downgrade aspect. I love the different play modes. I still find myself going back to the original, but having fun with Shift II as well!!!
I'm glad to hear you're having fun with it! If you wouldn't mind dropping a rating on it when you have a sec, I'd really appreciate it!
