If you’re in for a bit of Flash goodness (and some delightful B-grade hilarity) check out Robot Dinosaurs That Shoot Beams When They Roar. It’s fun, short and possibly the most kickass thing you’ll come across all day.
Ironically enough, it also stands as a fine example of how a joke can earn more of our playing time than something which is actually, you know, a proper serious game and stuff.
Indie development moral of the story: dinosaurs are awesome. Really awesome. You’d better go put one into your game right now.
