I'm not really one to replay a game once I've finished it. When I used to have cartridges and discs and I finished a game I would sell it. I was never one for collecting and keeping everything.
Nowadays... I buy all my games for Xbox One digitally. One negative aspect is that I can't sell the games... but the fact that I never have to switch discs again outweighs everything for me.
That is a good point, the selling back of it.
Your Nintendo switch does still use a cartridge if i'm not mistaken.
Yes, basically that's my kids console nowadays... and I plan to sell games they don't play anymore for them.
The cycle continues :p
