It would be nice to be able to make some family or guest subaccounts under my main account and have them able to access my library of games. I sometimes will have friends over or let family members play on my Rift, but it would be nice to let them create their own username instead of using mine to avoid Oculus friends thinking I'm online and ignoring them. I usually have to set my settings to appear offline and let people know it's not me playing to avoid having invites sent.
With my old Nintendo Wii, we'd have one console, but we'd log in as different users and play the games from the ones available. We didn't need to buy separate games for each user account. It also helped to keep track separately our progress in each game.
