That might not sound like that, but I would still keep a console like this. It could be worth more.
Well, I need the money now that I still need 100 euro to buy the PS5 (yes, I can get the PS5 from a friend for about 50 euro more than the original price)
Oh, then maybe look how much the 2ds cost if it is still relatively new and then you can roughly imagine how much it would be possible for.
Take a look at ebay.
You can also filter by completed / purchased offers.
This should give you a relatively meaningful price.
There's always something with 40 euro including 10 games, that is far too little. What price would you personally pay if you were to buy a Nintendo 2ds for your little cousin, etc?
What ebay spits out for me.
Supply and demand.
If people are not willing to pay more for it, then you should live with the fact that this is the market price.
Wait 20 years then you can easily sell it for 300 euro. And by then there's already the PS6, then you just buy the PS6 :)
