It can run Asphalt and some other intense games. You can use your iPad/iPhone as a controller, local multi player is possible for up to 4 people either using any iOS device OR the new Apple TV remote. I could imagine it running some ROBLOX games, it would be interesting for the ROBLOX team to experiment with it.
We get it, you’re hyped about upcoming Apple products.
The same action applies to this as it does to everything else. If it really takes off, ROBLOX will look into adding functionality for it if it becomes worth it.
