Yeah, it's VX Ace. The full version. (I got it for like 75% off during a Steam sale and got a crapton of DLC via the Humble Game Making Bundle)

You're about half right on the character generator thing. I used a seperate program designed to work with RPG Maker to create those. It was like 99 cents.

And yes, it is kind of difficult to get the hang of. (Why do you think the game's taking this long?)

Thanks for the support, Mig!
