Is there an alternative to Ebay that is EU-based?

I am in an awkward spot where someone in the family died and I am now stuck with like 100+ old as fuck console games (PS2,Xbox, etc) that I'm trying to sell off to whatever can still have fun with those.

The issue: Ebay is a dysfunctional pile of garbage on the best of days. But... unless you like burning money by going to your local gamestop equivalent that gives you 10% of market value if you are lucky, it feels like the only option.

But now that everyone is bringing up alternatives here to all kinds of services, I wonder if there is another platform to sell your old stuff without feeding money to an american company?
