I did, ofcourse.

1. In my opinion all default multiplayer levels suck except for Diamondus Warzone.
2. I never really played Single Player mode because it seemed so boring. (I don't like 2d shooting games anyway) -_-

But, because of JCS, I like JJ2. If the poll was about how JJ2 was in total, then I'd have given a 7 or maybe even higher. I like JJ2 because it's so customizable, you can make your own levels, tilesets and even use your own music files. If it weren't for that, I'd never have let my friend install JJ2 on my PC, or deleted it right after.

I'm a little critical when reviewing games. There's really A LOT needed to get me satisfied.
