Sorry Billy, but yeah, it IS awful.
I was incredibly stoked about this game, waited for almost a year from the time it was announced and bought it the day it was released.....
... and it was awful! Yes, the mutation system is a lump on a log, especially compared to previous editions with Life Leech and Gamma Eyes and Telekinesis, but what did me in were the psionics and nanite rules. If you were psionic, you advanced your ability in it not by feats, PrCs or even leveling, but by just doing it. Once psionicly active, you could crawl into a corner and practice your way to divinity. And for the nanotech, once again, you didn't get access by a class or feat, you just found it (or more correctly, the DM decided if you could have it or not), and once you had it, you could do just about anything. Make a laser pistol litterally out of thin air, or just shoot a laser out of your arse without the gun. I think it started out as a half-assed way of explaining all the fantastic elements of previous editions ("he didn't shoot lightning from his hands, he made his nanites do it!"), but the execution blew.
Run, do not walk, RUN away from this steaming pile. Go buy Darwin's World (2nd ed), which is pretty much like what GW used to be like (before they were obsessed with being "whacky" and was still the original, high-lethality, survival of the fittest style game). Not to mention the fact that DW is still being supported. Omega World is good, but mainly aimed at the Thundar the Barbarian style of play.
