What to get next

I've resisted showing my collection on here for a long time but here we are, I've finally relented. You could say I've been collecting since 1998 as I've never really stopped buying N64 games. A good chunk of these were bought from 2007-2009, back when the prices were much more reasonable. I still have all my original stuff from when I was a child, comple with the boxes.

I'm rather proud of it but I do feel like I've hit a bit of a brick wall with this collection though. Are there anymore PAL gems that I'm missing?
