DSI

It was ok, mostly. 4 moves per dino and critical hits and all that. The T-rex boss battle at the end was a little cheap though. He was really overpowered, and when you recruit (not capture) him to your team he is considerably nerfed down to a pathetic level.
I'm not sure if it was called dinosaur king or not.

I do hope they stop bringing out the brain training stuff, though that doesn't seem possible. They're gonna see the camera on the DSi and go 'look, that can see your face, let's make a training game out of that!'

Don't most games (appart from pokemon) do that will all bosses where they are nerfed down once to get them...

They might do, but then that's only fair so that the rest of the game isn't a total pushover. It's just that the T-rex was completely overpowered and walked through most of the team, and when you get it, it struggles to overcome even the dinos that were fought before the final battle.
