There's not a single video game with a prehistoric setting that takes itself seriously. All these games - mostly platformers - look cartoonish, have ridiculously wacky yet lovable main characters and never really cared about the few million years that separated dinosaurs and mankind.

Maybe it's bad timing or just bad luck. But there's a growing list of cancelled 3DS games. That's not good.

And the back.

While the Nintendo 3DS won't be out in Japan until next February, the handheld is shaping up to have a solid array of games. Hudson is the latest company to reveal its working on titles for the portable.

Hudson Entertainment will be reviving two of its oldest properties, expert headbutting caveman Bonk and turn-based strategy game Military Madness, with two all-new games, the company recently announced.
