Expensive in the context of other VR games sure. I couldn't find any official numbers but i'm sure it pales in comparison to dozens of other games that came out this year.

Also i'm not sure what these single player relatively short playtime/runtime games accomplish as you buy it play it in less than a week and are done. What I would like to see is the large scale infinitely playable MMO type game done on VR with at least at 250M budget.
