> I’ve played games that are a lot worse…

These things aren’t mutually exclusive. This can be an awful game (which it is) and not be the worst game ever made. And as with anything, it has its strong points too, just that as a complete package, it can’t be called a good game.

If your scale has only good and awful, you miss nuance.

I don't think the same adjective should be used to describe both both Trolls on Treasure Island and Silpheed. :P
