How much to I have to pay for this game? Will you have a kickstarter? Can I donate any money?
No member of the team, nor the Super Smash Ponies team as a whole accepts donations. We do not, nor will we ever charge for the game, nor make advertising revenue. As this is a fanwork, we can not and will not receive compensation of any kind. No money from donations, no money from advertising, no money from crowd-sourcing. Not a single penny, ever. The core team is footing the entire cost of the build. This is a work of love.
