I own a GOT Premium, but I'd love own a ST Premium someday, too. GOT is great, but its ruleset is so complex that it's not a game you can really just go out and start shooting stuff around. Even after a year, there's still a lot about it I don't understand. I also kind of miss having the open playfield. ST Premium doesn't look as good as GOT, but it's the kind of game where you can get immediate gratification more easily, i.e., you can forget about a mode and just concentrate on hitting the Vengeance money shot to start the multiball.
