Considering how much it has expanded, it might also be a worthwhile point to enlist minions to handle some of the nitty gritty detailing. A coder to implement/ expand some of the systems you've been working on, or an artist for example to take the load off scene work or asset creation. Assuming you are getting enough money to expand the team in that way anyhow.
Anyway long term fan, glad to see it still going and always enjoy the updates. Hopefully I'll be contributing again soon (ish).
