Is there anyone out there who would be interested in this sort of thing? Maybe I'm just odd.
You are not odd. I have done this many times on my own, trying to create worlds for my games to work from. I'm not exceptionally good at Perlin Noise or anything, but a few fancy algorithms definitely can do some neat tricks
Have you ever played, or just started up, Dwarf Fortress? What you are describing sounds similar in design. Create the world, make a history, weather and all!
Would this project be for ASCII / tile based games in particular? Or are you viewing this as a more 3D or 'floating point' based system? Tile based stuff looks well enough with tile based games, but making a tile-based world for a 'floating point' based game make it looks silly a lot of times (from my personal experience).
What programming languages do you use in particular? What graphics libraries?
C++ and OpenGL, by chance? I wouldn't mind sending you some code of what I've done in the past, though a lot of times you will not be impressed at all.
The use of this type of program / tool would be handy for those who wish to have something like this, but those people might be few and far between (especially looking at the above responses). I myself had thoughts to make huge games, massive and deep. But I find that games are best when they are games. When they are fun
And I can't seem to make fun things from crazy algorithms anymore.
Anyways, thanks for asking, you can email me and we can talk more if you like
