I keep a n64 around for Waynre Gretzkys 3D hockey. IMO the first enjoyable and playable 3D polygonal hockey game. We played it so mich back in thr day and it still plays well today. If you havent played it, and have anyone who like llayomg arcade style sports games with or against you, do not skip WG3DH.
That being said I only have two controllers so I can't get 2v2 gamrs going, and I never got the original smash bros. By that point of the N64 lifecycle I was in full blown PC gaming and emulation mode lol. I might be interested in those bits from this lot if you split it up
