Yeah, it's about time someone made another game with dinosaurs. The last decent game I played that had dinosaurs would have been Dino Crisis and various parts of the Jurassic Park franchise before it seemingly died (they're doing a new trilogy in time for 2012, though).
I play the HL2 mod of this and you could shoot nazis and dinosaurs in a linear-style shooter. It was.... meh.
But still, after looking at this trailer I have to say it looks hilariously fun.
