I got the first one for free on Epic. Enjoyed it enough that I bought the DLC for it, and was pleasantly surprised that my friends didn't need the DLC in order to play it with me, it was great!

And then about a year later I returned to the game with a different set of friends, and was no longer able to access the DLC until my friends also bought it.

It was a huge let down and I'm still pretty disappointed they changed that. I'm very skeptical this will stay this way.
