Well, just came over from the rpgmaker thread and I have to say this is a pretty solid concept. I look forward to seeing this released. However, if I may offer a word of advice, it doesn't look like you're experienced with rpgmaker, so I suggest you shouldn't try to implement too many features, or features that are too complicated. I'd hate to see another project cancelled because the developer bit off a bit more than they could chew.
(you may choose to disregard this, but a particular fetish of mine are hypnotic triggers, so I'd love to see this written in somehow)
