tough pick between witch's wish, the overlord ds game, and the power rangers Dino thunder gamecube game. chose with's wish since it's the most nostalgic to me. very cozy game with a great soundtrack.
the power rangers game is a close second, wasn't really much to it other than playing a giant robot dinosaur and destroying stuff but that's more than enough for a kid. it was pretty cool how they included several bonus maps and zords based on earlier power ranger series, game had a lot heart put into it.
the overlord ds game was pretty whatever, just a little strategy game with an overlord look put over it. I just love the overlord series and think it's neat that it had a ds game.
