Out of the 3 listed I only have Max, so...Max! I've enjoyed it so far. It's got some interesting puzzles and platforming and the marker controls, while not perfect, work pretty well. I didn't finish it yet but I'm on the last chapter (I think at least) and would definitely recommend it.

I'd say Max is the better game by far. Not saying the other 2 are bad, but Max is really good, especially for $15.
Crimson Dragon has a lot of content for what it is and it does have RPG elements (leveling dragons and getting skills). The microtransactions are for jewels which you can buy crap in the shop with. You can also play Classic difficulty and unlock jewels that way.
Halo is fun, but the stages are very short and the game is also very short overall. It has pretty decent replay value, but not enough to recommend it over Max or Crimson Dragon.
You can level up and evolve your dragons on Crimson Dragon. It's a great game and definitely worth the money.
Multiplayer is supposed to be added to Crimson Dragon later on, but right now you can only use the dragons of other players to go with you on missions to help you out. My Gamertag is Wapayos for anyone else who plays the game and would like to add me. It's the only game I have for Xbox One right now since it's the only one I'm interested in so far.
