I managed to get in. I like it... its definitely got some flaws, but overall I like it. It is definitely a MMO, especially where ground combat is involved, however I don't agree with people who are saying its like WoW. I confess I played WoW for about 3 years and finally left because everything got easier, and easier, and easier. STO right now feels like your standard MMO with away missions, and kind of a space combat game lite for the space missions. I kind of expected to be similar to Legacy since I know they were trying to make it accessible to as many people (read, customers) as possible, and I think they surprised me a little by actually making it slightly more complex, and better, than Legacy's combat system. I think I share the same feelings as everyone here that it would have been spectacular to have Klingon Academy style space combat, but I also know when a company like Cryptic is trying to get as many people as possible involved, they're not going to make something that would be niche. (Which, really is kind of sad, but the damn kids these days don't know what games should be like.)
Things I like so far: Space Combat is fun, the interface is rather minimalist (shows you just what you need to know), and I feel like a general Bajoran bada** most of the time.
Thinks I'm not liking: Feels buggier than a beta product should be and how too many things are instanced. I want to stress the "buggier than a beta product should be" bit. In my professional experience beta tests are usually metered pretty strictly and we've managed to take down the login servers at least once every night since they started the test last week. Its pretty apparent that they do NOT have the infrastructure yet for a full launch, but I realize that's also a nasty habit that a lot of the MMO publishers have. You're wise to wait 6 months SC.
Bottom line is that if you're expecting a MMO-sim you're not going to find it here, but if you want a fun Star Trek MMO to play with friends, I think they've delivered pretty well. The game, even with its bugs, is just plain fun. I haven't had to grind yet which is just spectacular since I cannot stand grinding.
