Not a super-huge collection, but I'm pretty happy with it.
3DS/DS and Super Famicom on the top shelf, found the SFC in my gf's mom's basement, amazing find.
Wii/Wii U and PS2 on the next, made a concentrated effort to collect the best games for both systems.
Game Boy near the bottom (followed by random board games and CCG stuff).
Also a small Steam collection; I've only had a gaming PC for two months, but I've been getting games on sale since last summer, since I knew I'd have a good PC at some point. Really loving it!
I don't have too much I want to add in the immediate future, not too interested in PS4/XBONE stuff, might try to snag a Virtual Boy at some point if I can find a good deal. Will eventually be down for an NX a couple of years after it comes out (just can't go in on a brand new system, even if it's Nintendo, until there are a solid 5-7 games out for it that I really want to play). I've got Smash, Splatoon, and Wind Waker HD downloaded on my Wii U, in case my small Wii U collection seems to give the lie to that statement.
Would also love to mod the Game Boys with a backlight and to get an artist to do some really dope art on them.
Would also like to get a case/cover art for my loose Skies of Arcadia Legends...how easy is to track something like that down?
