I tried sending this as a personal e-mail, but that effort seems to have crashed and burned. This might reach more members of Hero6 anyway:
Hello, I'm the sole programmer of a 2.5D RPG engine (3d characters and items, static 2d backgrounds) for which I'm building Quest for Glory I 2.5D in 800x600x24. Check out the newest preview I built:
http://www.agpgames.com/QuestforGlory.html. I'm writing to ask two things: do you have the backgrounds in at least 800x600 resolution, and would you be willing to surrender them to me? I"m quite confident I could finish your game fairly quickly and all due credit will of course be given.
