Persona 5 Royal most recently. I beat the original P5, and I'm interested in going through Royal at some point but I've been way more focused on RE3 Remake, FFVII Remake, and Animal Crossing New Horizons to really give it anything beyond a quick bootup, since despite a few major changes even in the opening scenes, it feels a bit too familiar and I'm really, really caught up in all of the "newness" of the other games, especially since I finished P5 feeling like it had nearly exhausted my patience with it due to the pacing of the back end of the game.
Right now, Trials of Mana is this way but it came out in the middle of my work week so I've only had time to squeeze a single session in. It will probably be a single-session experience until I manage to wrap up FFVIIR, but I like what I've played so far (as a fan of the original) and I think I will commit hard to it after I clear FFVII.
And I had this happen with Super Mario Maker 2 as well, but my single session was a chunky 5 hours or so. I just haven't gone back since I played through a good chunk of its built-in campaign and a few user-generated levels. It's a great game, but again there was a sense of familiarity having played the original Super Mario Maker that kinda caused the appeal to fade after that single session.
