Well, what I think this shows is that Cryptic has done an excellent job creating the right look for one of their games; I only hope that STO sports graphics as well-suited to its demographic as CO's are to its.
Stargate Worlds is shaping up to be quite pretty, indeed, and having played Tabula Rasa on the highest of settings I've certainly acquired a taste for high-end graphics in MMOGs. However, I agree with knighofhyrule730; SWG graphics are fine for ground-based gameplay (the only problem being that low-end graphics may convince people that they're getting a low-end product without giving it a fair shot). In particular, a great thing about the graphics in Star Wars Galaxies is that you can notice rather small details about people's facial features (those of Humans, in particular), and I think character customization is important to many Trekkies.
