Do any of you play indie/freeware games? You know the kind that get put on Kickstarter? Here are some of my favorites: Embric of Wulfhammer's Castle Shut Up and Jam Gaiden. I also can't wait for Shovel Knight.
Not freeware, but I really liked Antichamber. It's a 3D puzzle game meant to bend you mind. http://www.antichamber-game.com/
...Fighting is... Magic... [video=youtube;RwePGV289tY]http://www.youtube.com/watch?v=RwePGV289tY[/video] But seriously, Cave Story and Spelunky. Also, The Way, which IMO is easily the best RPG Maker game out there and one of the best RPGs around in general.
I quite liked Snakes of Avalon. Fair warning, it is a bit strange, but I really enjoyed it. Ben There, Dan That and the sequel Time, Gentlemen, Please! are both hillarious games in my opinion. And I'm obviously going to namedrop Hatoful Boyfriend here as well, because, you know, birds.
