I currently play EVE Online: The Second Genesis.
I'm not one for action, first person shooter games. This one has a little bit more mental numbers-type intelligence going for it. A lot of strategy, module swapping, economy based number crunching etc. If you're one for a normal paced MMORPG, this one may be for you. It's a cross between
Star Control II and
Trade Wars 2002.
The next expansion is currently being added to the game as I type and should be ready in about an hours time.
There is a no-hassle one month free trial. Check it out:
EVE Online
If anyone is interested, my in-game name is Lochlann.
