To be honest, I don't keep track of my games by region - it's all done by format. So, knocking up a list would take me too long so here are some estimates -
(As I'm from the UK, US & Jap count as Import to me)
All my Neo Geo AES & CD Games
About 30 Japanese Saturn Games
About 15 Jap & US DC Games
About 10 Jap MD Games
All my Virtual Boy Games
About 10 US & Jap SNES Games
A handful of imports for GC, PS2 & PS1
Think that's about it. I expect my import collection to grow a little as I slowly pick up more Bemani stuff.
