Just a question to admin, and to see how others feel about this.
Any plans of the ability the create mods and/or plugins for the game in future? This could allow for private servers with custom content in them.
(Once the game is big enough to control this, I know the dev doesnt want to lose the grip on his game by giving people freedom like this yet.)
Along with supporter bonuses, you could offer monthly server slots.
(Say the admin pays $20 for a server, he could then offer it as a slot for someone to rent, for $30 a month, figuratively speaking.)
