Some older ps2 games like monster inc and finding Nemo sell for like $100 last I saw. Before they mastered them for modern consoles, kingdom hearts was about $60 for ps2
There’s a lot of old games I still own or fondly remember across a lot of generations that got really expensive now. One of my favorite rpgs for ps1 was Lunar:Silver star story, and it goes for over $100 still.
Then of course on snes was Chrono Trigger. If you have that game and the box it’s worth $500 to $1200. A lot more than that if it’s an unopened copy.
