If you want to create an adventure game but your visual skills are lacking, I recommend looking into text adventures! There are great tools for making them these days:

- Inform 7 has annoying syntax but an amazing IDE;

- Inform 6 is somewhat object oriented, has a good Emacs mode and decades of tools;

- Dialog takes the evaluation model of Inform 7 and dresses it in sensible syntax but it is a bit niche so tools are lacking;

etc.

The Wise-Woman's Dog is one of the best adventures I played in 2025: https://ifdb.org/viewgame?id=bor8rmyfk7w9kgqs
