Voted..I said original Zelda. Just saying

I voted for ET on the Atari.  And I just realized that if we use his link he gets more entries in the drawing...stop using his link.  Use this one instead (direct lnk) https://www.playfire.com/bestgame/9SHBE6

I vote Company of Heroes as a great over all RTS

I find the vanilla company of heroes to be very unrealistic and unbalanced compared to the Blitzkrieg mod.

If I didn't include mods for games, my favorite RTS game would probably be Empire Total War.

My favorite multiplayer FPS game, of all time is Battlefield 2. ( I would pick Battlefield 3  but it has no LAN or mod support).

Far Cry would definitely be my favorite single player FPS game, and probably the best overall game. 

Favorite console game: Super Mario Bro 3.
