Well, I can now say with confidence that STO is freaking awesome. I got into open beta today. After downloading, installing, patching, etc. I only played about an hour (going to bed now) but it was a pretty sweet opening hour. The ship combat is superb, and the ground combat, while perhaps not quite as stellar, is still pretty great. Most of the issues I had with ground combat were just response issues, which theoretically would be fixed post-launch anyways.
Anyways, I highly recommend this to anyone wanting to trade the WoW habit in for something a bit more spacey.
