I've been toying with an idea for distribution for My Life as a Spy, and wanted to see what the player community thought. Here's what I'll probably end up doing.
First, I'll offer subscriptions for hosting privileges only. This would give the hoster admin rights on a discrete MLAAS world. Characters saved on one world would not be transferrable to another world.
Worlds would be named and registered through my allhands server. The name of the world would show up for a live game, so players would know which one was up. The registry would also be a place for hosters to post their regular hosting hours (if any).
