I will have to give it to Divinity Original Sin 2. Improves massively over the first and I sunk so many hours into it during early access and at launch. Persona 5 comes a close second, the only reason it didn't get my top spot is it frustrated me as much as I enjoyed it. Being told to sleep by Morgana made me want to kick that cat so hard especially on days where I hadn't done anything and it sent me straight to my room, couldn't even make lock picks.
