As for me, just one comes to mind:
UNLIMITED SaGa - SaGa Frontier was an excellent game; this is a new SaGa game -> this should be an excellent game, right?
I tried hard to like this game, hoo boy, I tried. But after ten hours of non-stop reels, I just couldn't take it any more. Absolute worst purchase I have ever made, as I bought it at the full $50, and most likely the worst I will ever make.
