A quick look at my steam library: wow carries 2139 hours, Battletech 886 hours, Rimworld 791 hours, Pathfinder 491 Hours, Skyrim 393 hours. Thats just my steam top 5. I likely have at least 3000 hours each in Minecraft, Battleground Europe (ww2online since July 2001), and Neverwinter 2. The civilization series are probably my favorite all time line of games given the sandbox nature of this grand strategy game. So that's it.
