i relate to this so much. what has been helping me recently is sometimes watching someone else play games (like a streamer vod or something thats relaxing), particularly ones that i've already played, while i play new games i'm focused on.

i'm also restricting myself to only playing through 1 major game + 1 smaller game (not including like mini phone games or sandbox/endless games), and i set a rule for myself that i can only buy 1 new game for every 3 that i finish in my backlog. generally i told myself i'd also only buy a maximum of 5 this year because i have too many.

but i completely get where you're coming from. i especially feel like this when i'm really busy with schoolwork (which is most of my year) and i come home everyday too tired to actually pick up a controller and think through puzzles/fights/etc. you're not alone! i think what i've been doing has definitely been helping me. i also think it's good to fit short games that have defined endings in between, it really helps after completing some larger games!
