This game is an insult to How to Train your Dragon, while it is cool that you can all the dragons you see from the movie, as well as new dragons, the game sort of falls flat after that.
The game has a nothing story, where the obvious antagonist, is going to cheat/use a new dragon, which you can later unlock and use. Customization is cool with you being able to customize your dragons to look how you want.
Burk itself is very bare bones, not that interesting to explore.
Also when you're game breaks down between: Flying through Rings like super man 64 (not saying the flying is bad, just it's literally just riding through rings lol) and the fighting which I don't exactly remember, except it was extremely easy to use.
I remember at max this game took me about.. maybe 10-20 hours to complete, considering I was a kid when I got this game. But now thinking more clearly I honest to god think this game could've been completed in about 3-4 hours which makes me kind of mad.
