If we can re-use an existing environment from one of our in-person rooms, the costs to get something like this up and running is marginal. We'd wind up getting a second playable experience, with a potentially wider audience, for not much more spend.
That said, this experience was purpose built to experiment with the remote game concept. (At the time, we weren't sure how to adapt our existing in-person games.) It's a small physical space (approx. 11ft x 9ft), and we used a ton of props we already had.
