It's a excellent piece of work that you did. Actually I do have a 2D Game Engine (made with XNA 4.0) that I am about to release for Christmas. It'll include RPG scripts and lots of features (please check on www.geexpowered.com)
So far I am using RPG Maker XP as a tile and event editor, then I import datas to xml so I can use them in my engine.
So I was wondering if we could combine our work, you on the editor side, me on the game engine side. Also I could help bringing some features into your Editor. For instance I have an Event Language that allows the creator to build events on the map and customize
their behaviour with more than 50 commands. I think that would bring a terrific added value to your tool.
Would you mind contacting me so we can discuss that ? my msn is roys(underscore)msn(at)live(dot)fr
Thanks and talk to you soon
