For me, the rarest things I own include:
Dead Space Ultra Limited Edition (limited to 1000)
Dead Space Dev Team kit (limited to 5000)
Art of Dead Space Clamshell (limited to 1000)
Bioshock Infinite Columbia statue (limited to 1000)
Dead Island Treasure Edition (limited to 266)
Demon's Souls Deluxe Edition
Sonic Generations Press Kit
There's probably more which I can't think of right at this moment.
