I'd like to see someone revive Blacklight: Retribution or make a sequel. Portal & Portal 2 were milestone games, of course, and they grew out of a school project. Limbo a fun and weird. Indie games are the future, too. I enjoyed Shadows of Adam, a Kickstarter-funded RPG.
I have moved back to tabletop gaming more and more of late. D&D, Kill Team, related model-building, various card games, and the like appeal to me more than these overhyped AAA titles.
