The ones that come to mind are:
- Fallout 3: Even i really enjoyed played NV a lot more, I was a total sucker for the whole chasing down your dad thing in FO3. Also the mission where you return to the vault absolutely killed me. Little touches in the environmental art had a big impact too.
- Bastion: Great characters, unique world, fun game.
- 30 Flights of Loving: Amazing amount of world and character building for a game with no dialog, still one of the my favorite video game experiences.
- Brothers: Just played this recently. I loved the various people(and other creatures) that helped you out, the bully at the beginning, and of course that last 10 minutes. never played a game that reminded me of old folk tales.
Also, am I blind or did we really get 2 pages in without anyone mentioning The Walking Dead???
