Not sure but you want 50% of players to stick around. Eve Online had to polish and revamp their new player experience multiple times because newbies kept quiting their first week.
A session should be doable in 2 hrs or less (a single RTS game). Vampire Survivors nails it for short and sweet but I love open ended creation like Factorio.
I played Divine Divinity some when it was released. It was interesting but clunky. It was no Neverwinter Nights.
I want to see us as gamers get away from sequelitis and get full games again without lock boxes or cash shops or battle passes. The excitement of Doom or Battlefield 2 or Elden Ring.
I mean the Bioware RPG.
