Well, I've had a little bit of time to play with Python so I started on the Ardentryst Map Editor. My goal is to make a simple, user-friendly editor that can just plug straight into any existing Ardentryst version.

HOWEVER--
Any current version of Ardentryst will not run custom maps. That is, you have to REPLACE the maps for them to be played.

In the next bugfix release of Ardentryst, there will be an
option to load custom maps!

Here's a screenshot to tickle your curiosity...



The colour scheme is customisable

Further progress, a map file can actually be loaded into memory and a splashscreen displays while the game data is being loaded.



(edit)
P.S. The version isn't really 0.4, I'm just lazy and am going to put it at that for now, it won't be released until at least v0.8 or thereabouts probably.

(edit 2)
It will be compatible with at least Linux and Windows. The python-tk module will be used, however I will see how a -notk commandline option goes. Is anyone against using Tk(inter)?
