If you're looking for more of an art program, I'd highly recommend Clip Studio Paint. It's really powerful and has a lot of tools, and it's a one time purchase. The base version is very often on sale for $25 USD. I use this primarily for art/drawing (drew my profile picture with it), though and I'm not sure it would be exactly what you might want to replace Photoshop, depending on what you 're usually using it for (ex. I probably wouldn't use it to fully design a TTRPG, but I'd use it to draw small pieces of art to add to a TTRPG. Although maybe it *would* still work and I haven't explored its functionality, who knows!)
