ohh, sim city 2000, what a classic, so much hours spent bulding cities only to destroy them later.
Since I have an old af PC, I'm playing some old stuff. I found em relaxing enough.
-Close Combat III: Russian front
-Rogue Spear series (rainbow six)
-Hitman (1 & 2)
-GTA 2
-Postal (1)
-Titan Quest
Also I have some oldies in Steam that are good: FTL (Faster than Light), Door Kickers, AoE 2 (HD 2013)
Think that's all
