if you miss mods, rejoice when bannerlord is coming: the game isn´t even out, yet a couple of teams are already working on their mods, making models, refining sounds, planning maps and game design systems, it´s crazy. I´d recommend to ditch the crpg code (let the sweet prince have his rest) and rather focus on bannerlord/okam modding. The good thing: Both Bannerlord and OKAM are based on C# which is, imo, easier to learn than C++. If you play around with the Unity-Engine a bit, you might also have quite some fun while learning C# by making a simple game.
Or you can also try yourself as animator, modeler, texture painter, audio dude, the sky is the limit
