So then, we can nail things down like: Jade Gully: Fang the Sniper Crystal Frost: ??? Red Sands: Egg Golem-alike? Metal Blade: Metal Sonic Death Egg: Eggman himself in some contraption Further considering that Senn posted up other zone tropes in music (thought I doubt they ever got any further than trope ideas), it looks like this wasn't going to be a very large game. That's par the course for the Saturn when you look at NiGHTS.
