I've played the mobile game Star Wars, Galaxy of Heroes pretty much since launch. For those unfamiliar, you collect Star Wars personalities from every official time era. Build an optimal squad of 5 heroes. Most of the arenas let you mix dark and light, but some make you choose one or the other. And then you battle opposing squads of 5, activating signature special abilities and finding the right winning combination.
It's one of the more fun mindless mobile games I play, and I feel like Destiny is going to scratch exactly the same itch, just in physical form.
