Should I sell my old Pokemon games?

[Abomination52]

I can sell them for like 40 - 60 euro which is around the price I bought them 10 - 16 years ago. Pretty sure I have basically every Pokemon game until Alpha Sapphire and Omega Ruby. Not sure what condition they're in though, would have to look for them.
Should I sell or keep for nostalgia reasons?

Keep them to remind you of your loser days

Pokemon gave me more dopamine in my childhood than women do now.

not worth it for couple of bucks that will lasts a few months, you should get a passive income
