Hmm... Let's see...
I think it started with seeing it advertised in Magazines and see Magician's Lord, 'Nam at the arcades. I drooled at the whole system but it was just wayyyyy too expensive for me to get myself. At one point CompuCenter (a computer/game console retail chain) was starting to phaze out their Neo inventory after two or three years. I went in there every chance I got to see how much the games were.
At one point they had a buy 2 get one free promotion, then it became buy 1 get one free, and then they marked the games 50% off. Still, there was no way in hell I could even shell out 125$ for a Neo Game, let alone the price for the system.
Days passed by but we'd still play Neo in the arcades.
When I hit 18, I had one of the best jobs I could have possibly gotten. A really nice-paying job working at a hospital. (I worked in their inventory, had loads of free time, was making close to 18$ an hour just to do data entry.)
I got the oppertunity to purchase a Neo Gold system with Baseball Stars Professional and Riding Hero, along with a fully decked out SNES system for close to 350$ off a person on a BBS. I sold the SNES system (I had one already) to a friend of mine for 100$.
Around then, the Neo got into the big fighting games boom and came out with Art of Fighting and Samurai Shodown. I hunted the games out but they were still in the 400$ range. Way out of my league (even at the time)... CompuCenter had long-since cleared out of the cheap titles they once had.
I kept the Neo for a few years, but ended up making due with the Arcade Card and other ports. I sold the Neo for close to the price I paid for it.
Then I heard of the NeoCD, but it wasn't available locally.
One day, I asked on the Turbo mailing list if there was a similar list for the Neo. Someone directed me to the DHP list. One of the first things I did was hook up with someone to get a NeoCD system. Then I started looking for games and joysticks.
When the NeoPocket came out, I went off and bought one. I kept buying games until they canned it in North America.
After a while, I started to think of getting a Neo cart system. (Especially after getting FF:RB2 on the NeoCD. ;P)
Eventually I stumbled accross the forum, and decided to go with an MVS + supergun route... And now I'll be getting a cab (most likely).
Every step I took, was a rediscovery...
However, I still remember drooling at the adds in the magazines. Hell, I remember reading an article on the Neo in Playboy. [A friend of mine had a subscription.]
