Some of you guys are far too quick to judge and/or pigeonhole people.
I bought my Dynastic Hero back in 2003 for $350. At the time, it was close to a high-end price for the game. Yes, I could have bought the Japanese version for about $20. Here are the reasons I bought it:
1. I wanted to play it. In English, NOT Japanese. This is actually very important to me. I hate playing games in Japanese.
2. I am a huge Wonder Boy series fan, and I own, and have beaten, every other game in the series released in the US.
3. I am a huge Turbo Grafx / Duo fan, ever since I got my Turbo in 1989.
4. I had wanted it ever since TZD sold them new for $50 (stupid me - should have bought it then).
5. It was one of the last games I needed to complete my complete Turbo set.
I was super excited when the game arrived, and it was the only game I played for the next 3 days or so until I finished it. It's been on my shelf ever since, although I have gone back and played it a few times since then.
The same sort of story holds true for a lot of games in my collection. I have been collecting a very long time and am very fortunate to have amassed quite a few very valuable titles, including 70+ Neo Geo AES games, a few of which cost even more than what I paid for DH. Did I play them? Of course I did. I can hold my own in any KOF, and I am unbeatable at Last Blade 2 with about 8 different characters. I also don't give a damn about "prestige" of owning games. In fact, this is one of the only times I have ever posted anything about my personal collection on any website, even Neo-geo.com, which I have been a moderator at for 9 years. There is a collection page there where people "show off" their stuff, but I have never been interested in other people gawking at my collection.
I have been fortunate enough, financially speaking, where I haven't needed to sell a game from my personal collection in years to free up cash, etc. However, if I did sell the DH now, I could probably get another $150 out of it above what I paid, due to its flawless condition and current market trends. In the meantime, if I get the urge to play it, I can pop it in anytime I want. If something crazy happens and I need money, it basically works out to me being paid $150 to own, play and enjoy a rare game for 5 years. Do these things make me stupid for buying it? Do I have more money than I know what to do with? Absolutely not.
Don't be so quick to conclude that people paying hundreds for games are doing so because they are idiots, or because they just want the "prestige", or that they don't want to play it, etc. It simply isn't always true.
