Why are XC2 and Torna still so pricey?

I'm trying to buy a copy of Torna, and I can't find any for less than 90€ second-hand. I bought XC2 last year and I payed something like 80€

Why are they so pricey after all these years?

Physically? Probably because they just didn't make a ton of them.

Xenoblade is more popular now than ever, and collectors love owning things physically.

If I remember correctly the production of the cartridges has been stopped so the price is now in full collectible rollercoaster

I hate this
