I did that a lot around 20 years ago, as I got older and started working and had too much money. Not just with games. Also anime, tv-shows, etc. Start something, get distracted by the shiny new thing, and never finish it. Ended up with literally 100's of unfinished games/DVD's/etc.
Nowadays, not anymore. I only play a single game and watch a single tv-show/anime at a time. Only start a new one once I finish the previous one or I get so bored and have no intention of continuing it.
This doesn't take into account a few multiplayer/gaas stuff like Mario Kart, Mario Party, Genshin, and since yesterday, Honkai Star Rail. I just play those whenever I have some offtime, or when with friends, whatever.
