My buddy, who owns a small arcade and routes games, purchased a brand new four slot when they were first released. I still recall the games: Art of Fighting, King of Monsters, Super Spy and Riding Hero. Super Spy was probably my favorite out of the bunch at the time. King of Monsters was another arcade favorite from the customers. It wasn't till I encountered another Neo 4 slot at a pizza place in a nearby town. This Neo had Magician Lord, Crossed Swords, Nam 1975 and I cant recall the other. Needless to say, I fell in love w/ Magician Lord (still my favorite).
Fast forward to '98, I picked up a modded Neo AES system. One of the first games I wanted was Magician Lord (paid a pretty penny for it at the time). I probably have around 20 games or so. Most expensive purchase was Metal Slug 3.
I still recall Babbage's had these games on their shelves.
On a side note, I wish there was a Magician Lord 2
