I have over 400 games, and 25+ consoles, and I have been collecting for about 2 years now. (Can’t add photos for some reason)

I work 3/12h shifts where I make a fair bit above minimum wage, and live w family, so I am able to spend some money without looking at the total for the most part.
(note, im waiting for my mrs to finish school to move out)

I am left at a bit of stalemate, where I feel like I am spending quite a bit of money daily, play the games, finish, then buy more. Got many games on the backlog, and I’ve been fixated on finding games I like, but I’ve been spending so much, and have suck little space.

I had the idea of selling the games I don’t play/finished/ have just cuz it was $3, but I have many who are valued at <$5.

I do like my very much full shelf, and I don’t quite enjoy the hassle of selling.
I’ve thought of GameStop or local retro shops, but they would give me a firm handshake, and a pack of beer.

I wanna sell these games, but don’t wanna sell them.
I wanna donate, but at the same time I don’t, ykwim?

I want more space for the games I enjoy, but I like my wall of games, and collection value. Sell, Keep, or donate? What would you do in my shoes?

My 8.5yr old son has been asking for a Nintendo Switch the last couple of birthdays/Christmas but the budget doesn’t stretch that far and honestly I’m not sure his attention span will stretch long enough.

Does anyone have any recommendations on a retro handheld console under the $100 AUD mark?
