I just bought 2 copies of DDR X2 w/ controller mat brand new for $9.98 each for PS2 today.  I still think DDR alway was and still is the best and most fun excercise game since PS1 and arcades.

I picked up DDR for PS3 a few months back but the songs were lacking (and too american) and Konami kind of changed the idea of instead of unlocking new songs they now putting them up for sale as DLC lol. 

I picked up Arc the Lad, Baten Kaitos, Resident Evil (GC  Remake) and possibly something else a few months back.  Havn't been able to play any of them to say the truth.  And almost half a year ago I went on a crazy Dreamcast buying spree.

I'm about to pick up Pokemon White 

Going to go and pick up conker bad fur day again.

I buy a lot of old wrpgs on GOG like Baldur's Gate and Planescape Torment.

I just buy random Gems for the PS2 for cheap got myself about 300 hours of JRPGs for 20$ last week so I'm set for awhile.

I just bought fire emblem for the gba and i bought a couple of n64 games too :)

Just picked up Baten Kaidos, Sonic Mega Collection, and FZero GX for gamecube a week ago. I played through Sonic 3, but that's about it so far. Now's a great time to buy old games you missed for super cheap. Awesome.
