Yea loved Fable 2, Fable 3 was a bit disappointing.
Assassin's Creed Black Flag was freaking awesome, I did really dig that game. I dont know how thd Diablo series fits in, but that was usually fun. They didn't feel like I had to commit hours a day to them. I could play for an hour and make good progress.
Couldnt really get into the Elder Scrolls games. Tried Morrowind and Oblivion, and both were fun, but felt kida lost at the same time with abundance of side missions. Oblivion definitely felt at bit overwhelming and time consuming. That's just me.
I've tried MMOs like DC Universe, Star Trek Online, Eve, but those felt like i had to play them for hours just to get anything done.
I think I prefer open space games, like X3 or Freelancer. I love to play games like World of Tanks or War Thunder. They're just fun to play and I can easily do it in an hour.
