Impressive collection, but very little that interests me... even on Wii less than half of what you have I would consider buying (or have bought in most cases)
Here is what interests me from your collection
1st of all, anything I have on my own collection of course
Any additional Zelda game I don't have (I think just the DS and SNES ones you have but I don't)
From Wii - MP:Trilogy and Muramasa (I suppose I would "consider" buying LKS and NSMBWii as well, but I doubt I would buy them)
From X360 - Mass Effect and Banjo-Kazooie
From PS3 - Flower, Uncharted1+2, PoP and Bioshock
From PS2 - ICO and SotC (mainly because I hear they are akin to Zelda games)
From GC - Super mario Sunshine
From DS - Animal Crossing
From SNES - Super Mario Kart
So from your 200+ games.... I own/have owned I think 10 of them, am planning to own 3 more (MPTrilogy, Muramasa and Super Mario Kart on VC when it gets to Europe) and would consider buying a further 16.
So yes, impressive collection, but your tastes are very different to mine.
