Town + Adventure map: ASCII tilemaps (could also be rendered bitmaps of ASCII chars instead of real ASCII chars).
Dungeon: First person viewport which is similar to what we have in early ULTIMA/MM/Wizardry games. Enemies appear as ASCII arts. Walls appear as vertical colored lines. There is no "roof" or "ground" in the game, to further simplify things.
The rendering engine should be flexible enough to be switched to graphics mode if needed in the future.
I don't intend to put up a lot of interaction into the game as it's too complicated for me. So you could say it's an ASCII version of Diablo based on Dragonlance.
I'll need someone to create ASCII arts for the project but I can probably do it by own (i.e. copy from somewhere else). I'll also need some 8-bit RPG music and I can grab some free ones for sure.
Stories have their patterns - there's the 7 Basic Stories, there's your tropes, 3 Act Structure, Aristotle's rules of drama, 36 Dramatic Situations, and so on. So I try to start with plot and character as those are usually the non-negotiable bits, and then expand into generating something interesting.
There's a prototype here which deals with basic character and plot tropes, but I'd like to have it follow more of a pattern, more characters, more customization, data, and so on: https://random-character.com/
I also had an idea of a platform to fight against the idea of scalping and ultimately give artists higher proceeds from ticket sales (though does not have to be restricted to concerts, think PS5 release type events as well), but I have not many insights in to the industry and am pretty comfortable at my day job for now. I think it could work because it would be possible to start small (do things that don't scale) but also eventually lead to a general system of handling ticketing and selling... but who am I kidding, I'll probably never do it :)
I'd probably want someone with more sales background, a big network, and knowledge in the target domain. And of course with a similar level of commitment and determination.
