More things to interact with in the Tower, please. I mean, the soccer ball and weird floating purple ball is nice, but why not add some Destiny-esque mini-games here and there? A unique game of cards to play with fellow guardians if you're low on Glimmer? Hunters seem to value luck, why not put it to the test in a small gambling stakes game? Maybe you can get a nice little mini-game to play on the road incase you want to kill time with a friend while waiting for something. Heck, maybe you can disassemble your rifle and as a mini-game try to reassemble it, possibly get some timed bonuses out of it too!
