Mt collection is a bit different as until I bought my PS3 in late 2011 I usually just sold my games, but I realized it really wasn't worth it and smarter to keep them from that point on, so a lot of my PSone, PS2, GBC, and GBA games are gone with exception to a select few.

3 GBC colour games (Link's Awakening DX, Oracle of Ages, Oracle of Season), 1 GBA game (Castevania Circle of the Moon)
these are the only games I've kept in near mint condition despite having no way to play them, I have everything including the small plastic bag the game comes in inside the box.
Persona Q, and Persona Dancing All Night art books
Mario Kart 8 OST (Club Nintendo Japan), Splatunes
Amongst other things I have all the SSB amiibo minus the DLC, SMB amiibo, Splatoon amiibo, and Animal Crossing series 1+2 and series 1 of the trading cards. My amiibo collecting has slowed down substantially as not many interest me. I had all of wave 1 and 2 pre-ordered before the fever broke out.
I also have over 100 Furuta Super Mario Bros. Choco Eggs across approx 10 different sets, 77 Dragon Quest Crystal Monsters across approx. 5 sets, complete set of Dragon Quest Monster Gallery HD, an entire set of Dragon Quest IX Character Making Figures series 1, and lastly an entire set of Hatsune Miku Selection Nendroid Petite. I also have various Hatsune Miku figures as well as the Project DIVA F accessory set, and Project DIVA F PS3 mini controller. I will be getting the new Project DIVA X controller once it comes out in August.
All of this surprisingly only takes up a very small portion of my living room and all my friends enjoy looking at them as well, it's just too vast to take pictures. I'm in to almost anything related to Hatsune Miku, DraQue, or Ryu ga Gotoku, as well as Mario.
