Kilton Online is being developed by enthusiasts, for enthusiasts. We're not in it for the money - we're in it for the fun, to make an FRPG that plays the way we think all FRPGs ought to be, and maybe, just maybe, to push the envelope of online gaming and do something that has never been done before. It will be a free download, and free to play, forever.
In the event that operating costs get to be more than we can cover (a nice problem to have, btw), we may introduce a donation system or paid membership levels. If that happens, rest assured, we intend to keep the playing field level: a paid member might get a special in-game perk (for example, a vanity title) but such perks will be purely cosmetic. Even if we do put a payment system in place, we expect that the vast majority of players will be at the free play level.
