Nice work on collecting everything. You should mod one of your systems and get going on relevant Japanese games. I only have Sin & Punishment and Custom Robo 64, but both are REALLY awesome games, so I throw those out as viable candidates.
Thanks. I have actually already modified one of them because I have the JPN version of Turok: Dinosaur Hunter which I found in a game store for $2 (before anyone asks, it is the same as the NA version). It's also possible to use a GameShark to play JPN games.
I've looked into imports before but there really isn't anything I'd want. Sin and Punishment isn't my type of game, mostly because I hear it is difficult. Custom Robo is one of the few Nintendo series I have never tried before but there is one on the GameCube which was released in North America.
Tetris 64 is one I've considered getting especially because it'd be cool to have the eccentric Bio Sensor accessory, but it ain't cheap.
theperm's punier then mop it up's n64 collection
It may not be great in number but that doesn't mean it isn't a great collection. You have a lot of the must-have games:
Super Mario 64
Goldeneye
the Banjo games
the Zelda games
etc.
And you have a good amount of the second-tier titles:
Diddy Kong Racing
Paper Mario
Star Wars Shadows of the Empire
Mario Tennis and Golf
etc.
And you even have some lessor-known and under-appreciated titles like:
Mission: Impossible
the Mystical Ninja games
Space Station Silicon Valley
Aidyn Chronicles
Beetle Adventure Racing
etc.
Really the only questionable games there are WWF Attitude, NBA Courtside, and maybe South Park.
Just a piece of advice though: Take those price stickers off! Those things drive me crazy!
