Here's the blog of my collection (yeah I know it's in french) but the pictures speak for themselves...if you want me to explain a part of my collection in detail (and in english) just post a comment on the blog or in this thead and I'll answer. I started collecting 2 years ago so there's not much obscure rare games but here's the list of my rarest things.
Metal Gear Solid Premium Package (US and JP)
Grand Thefth Auto III Kubrick figures (3000 prints)
Gran Turismo 4 Press Launch Box (0249/4000 prints)
