Just to clear this up. I am not totally new to PC gaming, I've played for a long time.
Now I have one that can play newer games.
I already played MMOs: EQI and II, FFXI, SWGalaxies, WoW, some free ones.
I got Half-Life, the day it was available (This was the last FPS I played on PC)
I was playing Duke Nukem, Doom, and Marathon when they were new.
Star Craft and War Craft, check.
I have played all 4 Civ games. Also Masters of Orion 2.
I had an Amiga 500 for god's sake.
I have many, many hours clocked in on RTS games. Age of Mythologies and Dawn of War are my current favorites, but I also play Rise of Nations/Legends and Age of Empires.
I play mostly single player, practicing for LAN parties.
I would cite regulation, but I know you will simply ignore it.
