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

What would be a better alternative in your opinion?

I really like wekan for this. It’s straightforward. Gets updates. And is flexible in terms of adding new fields to cards etc.

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!
