So the mobile app is awesome IMO. It would be really cool if there was a mobile game that tied into the full game. Here are a couple ideas that would make a fun casual mobile game and how they can tie in. 1. A puzzle game where you help the cryptarch's decrypt engrams. Rewards would be leveling up your cryptarch level, and a chance of earning engrams. 2. A top down shooter that uses your space ship so they do something besides look cool when in orbit. Rewards could be earning ammo synthesis, or motes of light, sparrow upgrades. Both games would earn you stuff that would give you perks in the main game, but not so much that it would give you a huge advantage over players who don't play mobile games. They would also give people who don't have time to play on the console all day to continue their legend and earn stuff throughout the day like the people that can afford to play all day.
