To stream Ubisoft PC games on Luna, you do have to own them
For clarification, this feature is targeted at Luna subscribers who don’t already have a subscription to the Ubisoft+ multi-access plan. However, having that will allow the ability to stream addition Ubisoft+ titles. So if you really love Ubisoft games, you may want to check Ubisoft+ out. That being said, a Ubisoft+ subscription is not required. You also need to sync you Ubisoft account to your Luna account to open up access. And any games you want to play, provided they’re available, will need to have been purchased from the Ubisoft store. Ubisoft games purchased from Steam or other clients will not count here. So keep that in mind. As for which games are available, titles like Far Cry 6, Uno, and Assassin’s Creed Valhalla are just a few of the games. But there are more and it’s likely Ubisoft and the Luna team will add in additional titles as time goes on.
