Geez, dude! That's aboput the worst question I've ever heard on TLR!
SL is a TOTALLY different game. If you like joystick-controlled space shooters, that's a must for you! Anyway, SL is a prequel to FL, telling the story of how everytihing started. A cool game, about the collest i've ever played.

It's better to be a worldwide known drunkard than an anonymous alcoholic!

<<< FreeLancer Spoilers >>>

StarLancer is a sort of "prequel" to FreeLancer. It takes place after (before?) the sleeper ships launched from Sol, and the Alliance has been ambushed by the Coalition. It is your job to fight as part of the 45th Volunteers to help turn the tide of the war.

If you don't have it, you can buy it for dirt cheap (less than $5) and it's a really great game, worth the 30-something I paid for it. It also has Joystick support which X2 fans would like.
