Well, I have an idea....
I run, as a SYSOP, a server playing Legend of the Green Dragon...a web-based text-based browser RPG, based on Seth able's Legend of the Red Dragon...a bulletin-board door game from the 80's.
Now, it would need a lot of modification, because in it's current form, it runs as a multi-player online game, and text-based.
Dingoo, not supporting online functions, would need to alter it to be a single-player game, perhaps going from text-based to actual real-time movements...
I have a number of custom modules for the game, too. I'd be willing to open up the source to you for my custom modules...the rest of the source should be open as it is published under a Creative Commons License.
It's currently written in PHP.
I'd love to see something like THAT get done, if it were ever possible to do!
