You’ll be waiting a very long time to find a 3D game with the depth in content and mechanics of Cataclysm because the development process is so radically different. In an ASCII game if you want to add a new item, you just assign it a letter and colour and then all the effort goes into the stats, description and mechanics etc. But in a 3D game you have to spend a lot of time designing, modelling, texturing and rendering stuff and it leaves little time for developing mechanics to go with it.
I swear as I’ve gotten older I’ve really begun to dislike 3D games in general, they’re usually ugly and extremely shallow, even the WOWGRAFIX games don’t impress me because I know that in ten years people will look back and say “omg we thought that looked good?” ASCII is timeless.
Cataclysm is as immersive as they come imo because you have to use your imagination
