How to Train Your Dragon
has pretty much the same premise as the Wii version of this game. Your father wants you to do well in the village's new dragon tournament, and thus sends you from one corner of the island to the other in search of various artifacts to help you on your way. Of course, most of the challenges you face along the way to fighting in the tournament, are, well, fights. There are no relationships to build with your dragon, and not much that ties the game to the movie other than likenesses of the main characters.
Battles are turn-based, and there can be a bit of fun found in creating a strategy to beat each unique opponent. All attacks and defensive moves have a time consumption linked to them. So you'll come across the choice of using lots of moves with low time consumption, or using heavy hitters with large time consumption. Status effects like burning or poison can also be applied to take damage while waiting for your time meter to come back up.
Along the way, you'll also get to make armor upgrades for your dragon, which involve a rather entertaining mini-game. You must pour molten ore into a mold, break it free of the mold, and polish it, all using the touch screen. Depending on how well you perform, your armor will provide better stat bonuses for your dragon. Other than this, you'll level your dragon's abilities by using them in battle repeatedly.
I'd like to say that there's more to the game, but that's pretty much it. Collect dragons, make armor, and fight other dragons. There aren't an abundance of dragon types to collect either, just the main types from the movie. A multiplayer aspect gives the game a miniscule amount of replay value. The multiplayer mode limits you to one-on-one fights which are pretty much identical to the ones in the main game. That's really all you get: no frills, no point system.
