A few minutes after
Sky suggested MOH, I downloaded the demo and beat it in about 2 hrs. It has AMAZING sound/audio to it, probably the best I've heard thus far. BUT, I there are a few things that irritate me about the game. It's not as "Free" of a game as HL and Quake. You are trapped or forced into going one way -- I guess that's the best way I can describe it. I kinda didn't like the way the during-game weapons menu was set up-- it was hard to change weapons quickly. When I run in the game, it doesn't really seem like running at all, maybe walking fast, but not running. Also, I had to really cut back on the graphics settings whereas with many of the games I've listed in my first post, I could just about max them out. There are a few other minute things, but overall seems like a great game. I may end up buying it. I'm gonna think about it first though.
I can definitely see myself playing just about any HL, Unreal, or Quake mods/add-ons so I will have to look into Urban Terror for sure.
Don't really like RPGs.
I have Deus Ex (it was free for me): the game is too complicated for me

I don't like the how the players are controlled.
I've seen some friends playing Everquest and talk about how addictive it is, but from what I've seen, it doesn't look like my kinda game. Maybe I'll take a closer look someday.
Thanks guys.
