Like, games that you have played through multiple times, but you still like to replay them from time to time because you can just relax and have a good time without too much hassle.
For me some are Dark Souls 1&2 and Borderlands 1, I can play them without too much thoughts about what I’m doing, but still be focused enough so no bad thoughts appear.
I was recently reminded of Shining in the Darkness for the Mega Drive and got super nostalgic. I might have to play that again.
The same thing recently happened to me with Descent 3. I’d never played Descent 1 or 2, so I figured if I was going to replay Descent 3, I ought to play the other two first, so I’m currently working my way through Descent 1.
But more to the heart of your question:
If I recall correctly, Descent 3 was made by another developer team and it was quite a different game. But Descent 1 and 2 are favorites of mine. Some of the original developers made Overload. Try it, if you haven’t already.
