Here's my little collection:
Got all of them except Excitebike 64 and NBA Hangtime new back in the day. I bought Excitebike 64 at some random little classic game shop a few years ago, and I ordered NBA Hangtime on eBay just a few days ago.
The loose copy of Star Wars Episode I Racer came from the N64 bundle for it, which was when my mom decided to buy a second N64 randomly. Hah. My brother has that N64 now, though (along with most of the controllers...). I kept all of the games, though, since his friends already own all of the ones that they'd play, anyway, and he only plays them with those guys.
I'm looking to get Mischief Makers and NFL Blitz next, but I'm having a hard time finding either boxed. Heh. I'm considering getting the former on Amazon through a listing that comes with a universal game case, but I don't know how that would look next to the rest of my N64 games.
Edit: I'm also thinking about getting Blast Corps, Indiana Jones and the Infernal Machine (which I rented once), Killer Instinct Gold, and San Francisco Rush 2049, among others.
I don't know if I should get San Francisco Rush 2049 on the N64 or Dreamcast, though. I know the Dreamcast version looks better and all that, but I do like the quick convenience of cartridges. Heh. Then there's also Midway Arcade Treasures 3, which has a port of the Dreamcast version in it...
Also, maybe I should start thinking about getting some games loose...as finding them with the boxes is hard, and can cost a lot more.
Speaking of loose games...some local electronics shop had San Francisco Rush: Extreme Racing and Fighter's Destiny. Should I pick them up?
Also, what do you guys think of the Castlevania games for the system? I'm eyeing some listings on Amazon for the first one.
