Actually, I dont think that Jazz Jackrabbit has never existed if its still active after more than 12 years after being created. But well, there are few things I'd like to see in that game. I'd love to see rabbits unable to use guns(there are even special animations for Jazz and Spaz if im sure - they are not holding blasters). But that's only one thing, I think that this is one of the best games made ever. Every game for which there are level editors are good, but Jazz you can create really simply your own "texture"(for which I mean tileset) and create a level using it.
That's the thing for which I'm still playing this game, it's just simple. Not bugfree, I probably haven't played any bugfree game. The second thing is community, small but really, I haven't seen a community like that at any other game. Maybe thats because I don't play internet games very often, but whatever.
And about the whole topic - quite pointless. If I'm sure, every of the bugs you "found" was mentioned in some article about jj2 levels at J2O. It's nice sometimes to talk about "what would happen if...", but you didn't even tried to, you just said that jj2 sucks. Do what you want, play Sonic or, wait what is your newest project? Making a jj1 set remake for this stupid, pointless game?
