I sold my Gamecube collection about 5-6 years ago. I starting looking up prices and I wanted the money more than I wanted the games. The only game I really liked on the Gamecube was Fire Emblem, but it's worth so much that I sold it anyway. (I think I got about $90 back in the day.) All of the other games gave good money and I had no emotional attachment to (except maybe Mario Kart...maybe).
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
