Ah, yes. The good ol' days of the Neo Geo...
Oh, wait. Those days are still going on in my house right now.
In what was the coolest graduation/birthday/Christmas present EVER, all of my best friends got together and rebuilt a Neo Geo 2-slot for me. It is PRISTINE - it has new speakers, a custom wood-finish console, new controls, new monitor, new everything. They also got me Samurai Shodown and KOF '94. After that, I proceeded to buy KOF '95, KOF '96, KOF '97, and Samurai Shodown II and IV. Great stuff - truly classics of the arcade fighting game genre.
I only wish I had more people to play against! After I would consistently beat the ever loving HELL out of them, they all stopped playing. *sigh* I need more competition!
