...It's pretty much just DND with numbers shifted around for a bit, the d12 and MP notwithstanding.
Unless its for someone whose never played DND and never would, there isn't much of a point using it. (Actually it might even mess people up if they ever used both.)
The thing where you don't get KOed until end of round though? It's pretty easy for GMs to abuse them by having a bunch of glass cannon monsters if they just want to kill PCs. (Self-destruct bomb monsters would be pretty scary here.)
