I like to play my games as chapters, when I know a game and enjoy it I tend to play the necessary to advance in the story wihout getting burnt out, for example nowadays i'm playing lego star wars the complete saga and I play 1 episode in a long session (1 and half hour for the prequels and maybe 2 to 2 and half for the original trilogy) same when i played a full world in plants vs zombies 2 or 2-3 worlds in a kingdom hearts game, wich usually translate to 2-3 hours, altough that's gonna change when I get a job, there's also the fact that there are games with a mission structure like red dead redemption or arkham origins, wich I usually do 3-7 in a row, wich translates to 1 and half to 2 hours, I also tend to just play while listening to a podcast, wich can sometimes wildly go from 30 minutes to 4 hours, altough this only happens if I have nothing to do, it happened the most with persona 3 and I've never even beaten it, got my ass since 2022 and it seems it still will until 2026
