That Shadow of the Beast looks... Well, some of the screens look like crap, too little contrast for such interesting organic designs. I think I'll vote for Shadow of the Beast. I've never played Amiga games in my life and I've seen some great pixel graphics there. This game should prove interesting to take a look at for someone like me (and I guess I'm not the only one who grew playing NES and few old PC games, so Amiga is new uncharted territory).
DoDonPachi is awesome, I would have voted for that one but that Shadow... Well, it's screaming "re-make me!!"
