Is this for game consoles only, or would stuff like experimenting with similar looking (low-poly) art techniques on modern computers be acceptable there as well?
I just started thinking about demakes and other such things while going over my YT subscriptions for content.
But while this is not strictly limited to consoles and that era, I'm gonna say no; this is mostly about systems, and not the style.
I almost created the community at !cool3dtechnology@suppo.fi, but didn't like the name for this purpose. I decided to maybe open it for shaders and graphics, from a gamedev-ish perspective. I think retro-lowpoly-graphics are cool and it would have a bunch of that.
Not the person you're replying to but wanted to share my 2 cents
You might consider keeping things broad given how small a platform lemmy is and how niche the subject matter is. I like the idea of them being separate but splitting community more than strictly necessary runs the risk of the community dieing without enough people having things to post. You can always acknowledge future plans to split, and make it two separate communities in the future
Ultimately you know best what kinda space you wanna make and how you wanna go about it, I just think your community idea is neat and wanna see it reach a stable number of active users :)
