When it comes to game collecting/selling, there's a small list of games called "evergreen titles". These are games that, regardless of when you're selling it, will garner a good price & sell relatively quick. The reasons vary, but are normally the game being considered:
- A console defining game (Sonic 1-3 for Genesis, Mario 1-3 for NES, Final Fantasy 7 for PS1, etc.)
- A small, "underground" hit that was overlooked during its lifespan ("Hidden Gems" are what they are normally called.)
The exact games depend on the system, but when it comes to Nintendo the evergreen titles can be boiled down to:
- Anything Mario
- Anything Zelda
- Anything Pokémon
The reason these sell so well is due to the buyer being one of two things:
- People who had the system that are now nostalgic and are most likely to have played them.
- New collectors who want to either jumpstart their collection or have the best games for a system, since they're closely linked to the consoles history/image.
