I thought it might actually be fun to do the companion app. It's not. It's simply tedious. Thankfully, the stuff in those chests is also lame and completely unnecessary. In the end the chests are simply a nuisance.
There were other interesting moments like this in gaming history, like when Secret of Monkey Island changed the way people think by removing death and game-overs, or when FPS's transitioned away from quicksave/quickload to checkpoint systems.
