Is Playroom VR something you can play alone or is it a two or more players kind of thing?
You need at least one other local player for most of the games. There is a showroom where you can unlock "trophies" via a crane game for coins you earned in the other games. You could spend some time alone in that, but it really is for local multiplayer. It's super fun and a great showcase though - and on top of it all it's free (in Europe).
