Valve got back to us with some keys to give to customers that previously purchased RPG Maker VX Ace through the RPG Maker Web store, before Ace was available on Steam.
To get your free key for Ace on Steam, just forward your purchase confirmation email to me, and I will verify your order. Afterwards, I will send you a key to redeem on Steam.
My email address is firstname.lastname@example.org
Keys are offered complimentary, not part of your purchase price here on RMW. Keys are only to be redeemed by the license holder. They are not to be given away/traded. They are NOT a second license.
