Best Classic games...

All the Dukes and Half-life.

I've gotta give it to the old LucasArts and Sierra adventure games, as well as some of the old-school flight combat simulators like Jane's.

X-Comthusaha

Yep, X-Com UFO Defense/Enemy Unknown....   It's still the best game ever made IMO.    

  Say it once I will say it hundreds of more times : Freespace 2

  The game is one of the best games ever made..  And is a free download now online, and always has been free (and legal) due to their wierd TOS..
