Are there any good space sims out there?

Eve Online. It's not SinglePlayer, only online, but it's is very well done. Great graphics, music, effects, PvP, and the options are seemingly endless. There are over 3000 Solar Systems you can go into, compared to the 40-50 in Freelancer. You can make corporations, have wars, mine asteroids, have squads, chat publicly or between friends, trade for profit, etc. Much of the stuff Freelancer has and more.

However, and I hate leaving this until last, but it requires a monthly payment of $14.95 (first month $19.95). For this reason I don't have the game. But if you want to try it out, you can get a free 14-day trial of Eve Online. It's on their website, which I'm sure can be easly found via Google.

Ya grab Freespace 2.

Use this link it is to the installer. It grabs all he files for you and its free. Thank you open source.

Its still bar none the best space sim to date. Its pure fun. Definitly one of my favorite games of all time. Plus this open source version has improved textures, aa, dynamic lightning and far more resolution modes.
