I have most of these games you pictured. KOF 11 is great and I had more fun with Neo-Geo Battle Coliseum than I did Marvel Vs. Capcom 2. KOF Maximum Impact 2 (Kof 2006) was surprisingly good too. Not to mention the Samurai Shodown anthology is beastly! (Just wish they would have included the SS V with the endings and bloody finishers as opposed to the inferior version that's actually in the collection)
At least by my definition you are hardcore enough. It's always a joy to yap with other SNK fans. Thanks for that!
