It's just your disillusionment with the community. I've steered clear from this forum for a long time (not because I hate the forum but because I wanted to avoid a time sink) so I don't have the pessimism you do. In fact, I probably respect the Neo Geo as a system more now than ever.
I think there are 3 main viewpoints towards the Neo Geo.
1. The 1st viewpoint is from those who were either born after the Neo Geo boom or didn't care for arcade games at the time. For these folks, the Neo Geo is a crazy antique that doesn't make sense.
First of all, I think piracy has done the most to tarnish the Neo Geo's respectability. From a sheik's toy and arcade wonder to something bootlegged and emulated the world over, the Neo Geo isn't looked at with any awe by modern gamers.
It doesn't help that these games were ported to so many different platforms and officially re-released so many times. What once were coveted games locked up in the magical arcade cabinet or after sacrificing $200-300 are now begging to be bought for a mere pittance of $5.
And beyond the huge supply available, the Neo Geo is also mocked for many reasons. The controls of many games are clunky. Most of the English translations are awful. The graphics have an antiquated 16-bit look (or 24-bit in SNK marketing terms) with noticeable individual pixels. There's some funky region censorship. The Neo Geo CD has an infamous reputation among the more knowledgeable for minutes-long loading times between matches. "Crusty old twats" who can't let go of the past pay $30,000 for select versions of Neo Geo games that Joe Shmoe can play for $10 (or "for free" as pirates love to say).
With all these factors combined, it's easy to see how gamers who weren't around in the Neo Geo era view the Neo Geo as a cheap minute of novelty with a ridiculous fan base stuck in the past.
2. The 2nd viewpoint is from Neo Geo fans who've fallen off throughout the years. Many lost interest in games altogether. After all, somebody who could afford Neo Geo games back in the heyday has probably moved on to cars and boats by now. Some have no interest in 2D fighting, the biggest genre of its day, anymore and now playing the latest FPS from today's dominant genre
Others may collect Neo Geo games for the purposes of amassing a collection but not care about actually playing the games anymore. Nowadays, it seems there are more and more of these folks around. I don't like the senseless hoarding of games since it's a lot easier to make money investing in other vehicles that don't involve depriving others of the chance to own a game. Unfortunately, there's little that can be done to stop these folks. If you already have a solid library yourself, then you might even want to thank these folks for helping raise the value of game prices.
Finally, there's a group of Neo Geo fans who've been put off by the community. Companies are illegally releasing games and selling them for $400. Illegal conversions going for ripoff prices are more common. People are ripping others off. Some game prices are much higher now. There's some drama on this forum. All this baggage that comes with being a Neo Geo fan can be exhausting sometimes and either temporarily make someone lose interest or make one quit altogether. I suspect this situation is the case with this topic.
3. The 3rd and final viewpoint is from Neo Geo fans who still respect the system. On the AES end, they still remember the intimidating but sleek AES system with what seemed to be an industrial-grade arcade stick for a controller. They remember seeing the incredibly expensive carts in huge, colorful boxes that cost more than a whole lesser system and were either dream purchases for kids or huge investments for older folks. They remember that despite the high prices, the carts were actually great values on a per-meg basis, as mentioned in SNK's interesting ads.
On the MVS end, these folks remember the big red cabinets at arcades that at any day of the week could pop in the latest and greatest game with eye-popping jumbo sprites. They remember how the Sega Genesis and Super NES were graphically no match and mangled most of the Neo Geo ports. They remember how impressed they were by the graphics scaling and crisp vocals. These fans can still look at Neo Geo games today and still appreciate the 2D sprite animation that in many ways hasn't been superseded by the graphics in today's 2D titles. They remember a time when certain arcade genres dominated the industry, genres that have lost much ground in today's video game environment.
I don't think the Neo Geo offers much beyond its pre-3D brethren but what's wrong with that? I think all systems of the 2D age are worthy of a healthy fan base right now. The Neo Geo's extra calling is that in addition to the console, many have fond memories playing its games in arcades against friends and rivals.
Anyway, I'm in this 3rd category. For years, I thought less and less of the Neo Geo due to its widespread availability in recent times. If we were playing word association, the first term that probably would've come to mind hearing "Neo Geo" would've been "emulation." But playing the games themselves and not focusing on external circumstances, I gradually changed my tune. Also, I didn't bother to immerse myself in the community here and still have no plans to do so. In this way, other Neo Geo fans can minimally affect my views on the system.
I have plenty of nostalgia for the Neo Geo's glory days and the pageantry that seemed to accompany the system. But even playing the games now, I'm still impressed with the content and fast-paced fun featured in many of the games. I could play most Neo Geo titles for weeks if I had time and if there was local competition around. After all, although not a Neo Geo game but rather a fellow 2D game from the arcade golden age, Super Street Fighter II Turbo has likely taken up 4000+ hours of my life.
Some early games are clunky but once the ball started rolling, it was clear why the Neo Geo received the fan base that it did. How each individual's viewpoints toward the system change is a question for the individual himself. But unless today's games start improving on Neo Geo titles in every way, which would require a significant shift in today's genres, graphics, music, mechanics, taste, and everything in-between, I believe the Neo Geo love at large will be here to stay.
