You should go ahead and list the latest purchases you got K-Man and include all the 2D fighters you had previously.
I'm assuming everything I bought aside from the stick itself.
A Ps3 adapter (which hopefully will work without a hitch)
a DC adapter
Fighters picked up this week:
Fatal Fury Battle Archives Vol. 1
King of Fighters XI
Capcom vs SNK 2 PS2 (to replace my xbox EO copy, kinda hard to find so I had to resort to ebay and ebay prices)
I have:
PS2
Street Fighter Anniversary Collection (PS2, Xbox)
Street Fighter Alpha Anthology
Neo Geo Battle Coliseum
Grabbing Fatal Fury Archives vol 2 and samurai shodown anthology when they hit
DC
Capcom vs SNK
Marvel Vs Capcom 2
King of Fighters 99
Soul Calibur
Powerstone 2
Thanks to Pyro I also own a bunch of capcom fighters for Saturn. However, I find the gamepad relatively satisfactory, although I may throw down 15 bucks toward a saturn converter at some point.
