Which is funny, because computer games didn’t have any kind of story at the beginning (look at pong, tetris, qbert, asteroids etc.)

https://en.m.wikipedia.org/wiki/Creation_Engine

The Creation Engine is a 3D video game engine created by Bethesda Game Studios based on the Gamebryo engine.

Gamebryo was called netimmerse until 2003. Creation is a modified gamebryo. So Creation 2 will also be based on it. So yes they use kinda the same engine since morrowind. Beteshda will not change away from it because gamebryo is a large reason why the modding community is as strong as it is for skyrim etc. And the modding community sells a lot of copies!
