I do! And it might be possible some day.
Clarvalon, who is developing the XAGE adventure game engine for XBox360 has taken the first baby steps to building an AGS to XAGE converter.
Currently, it pulls in all the sprites and backgrounds and allows you to walk around, but it looks like it’s not yet possible to pull in game logic. So, it currently does most of the grunt work for you, and getting the actual gameplay working is up to the developer. Still, pretty damn nifty. Nice work Clarvalon!
Hat tip to SSH for spotting this.
