Well being a big trek fan i took the plunge and decided to try Star Trek online as my first ever MMO, and i must say I'm really enjoying it so far, i have only started but it looks fantastic and im getting right into the swing of things, it will take me time to get to grips with all the nuances of the game, but i can see its going to be fun getting there.
Indeed, welcome to STO and the world of MMOs. I am having a great time in STO so far as well, but I have been playing since closed beta in December. Finding a good fleet only makes things better, as community is truly what defines an MMO. There are some great people online here.
Ah! But there are plenty of horses patooties out here! <LOL>
