Young folks can use dosbox etc... but it just does not feel the same compared to how it was "originally". I could not get myself to want to play raildroad tycoon again; I found it easy to play games such as civilization or UFO: Enemy Unknown (oddly enough the first part is more playable than the second part here).
Free (but gacha.)

Hard pass.
I personally haven't, because it would take the fun out of the game.
Right now, I am caught up with gfl2, and having a blast with Arknights: Endfield. The factory must grow!
In a few weeks, I'll probably be working on my projects and not touching any games at all, as I was just a few weeks ago.
Two years is indeed a bit too much. Got to do something else when it stops being fun. I had to learn that lesson with a few months of DOTA2; it can turn into a job, except that it produces nothing of value.
For me that's OpenMW
