>My issue has never been playing multiple games at once. My issue is leaving a significant span of time in between play sessions and coming back to a game I've lost familiarity with. This tends to lead to more games abandoned after months and sometimes years of not playing them.

Yes, this is exactly what I have as well. I can enjoy a game for hundreds of hours, but as soon as I find a game that is a little more interesting, I neglect the first game, never to return to it or return and have forgotten everything.

For that reason, I must have started games like Bloodborne and Skyrim a hundred times, simply because I forgot the controls or forgot where I was in the first place.
