I grouped with Keero, Gator Missile, and Corp.fox tonight and my experience...well, it didn't change my opinion.
This is still a game that isn't bad, but it also isn't so fun as to warrant $15 a month. The lag certainly hurts the overall presentation (even though it's an open beta in name and a stress test in practice), but the controls (both camera and movement) feel awkward, I felt like I was fighting the camera half the time during space battles, and losing half our party (Keero and Gator) in the middle of a fight with multiple ships didn't help.
Again, if you're a Star Trek fan or looking for a new sci-fi MMO, then check it out once there's a free trial publicly available.
As for me, I know that no matter how far I run, no matter how many MMO betas I play, and no matter how much I want it to be true...WoW is still my top contender for a paid MMO.
I can see how the space battles in STO
could be fun, but the awkward controls sap the fun right out of it. I'd love to find a game that's essentially a MMO take on the old space exploration games (most notably,
Starflight), but I don't think this is it--not yet. It's still open beta and too soon to tell. Most MMOs don't truly shine until 3-6 months after retail release or until after the first expansion pack.
