Origin first. Their games often seemed to have an extra effort put into them and be better than they had to be.
I miss Cavedog, of Total Annihilation fame. They went on to become Gas-Powered Games, but now their publisher is putting DRM on their games, and it's not the same. I liked it more when they were the underdog thumbing their noses at expectations rather than conforming to them.
Also, whatever the name is of the company that made the original NASCAR for PC. They long ago got bought out by EA, and eventually the franchise folded. That was an amazingly good game and important, influential franchise.

Lucas arts.
I like monkeys, especially three headed ones.

Look out, there is one behind you!

Yes, it was much better when Lucas bashed Sierra :)
Rubber tree.

SirTech.

hehe I wonder what that'll look like in the remake

Oh yea, forgot about that.

New World Computing. I like their M&M and HOM&M games, unlike that crap being developed for Ubifail.
