I'm a DJ a heart (thousands of records) so this is sort of an auxillary hobby for me, but there's some similarities. I've learned to be pretty choosy, like the Jiff moms. When you see a good deal, you want to seize the moment, but it's probably better to think about whether you'll actually keep and use what you're buying. After years and years of buying up records, I started to realize that if I'm not going to use it, then why am I buying it? It's a hard lesson to learn because your instinct is to act. We call it "digging" in the DJ world. I haven't stopped digging, but I've learned to be much more selective. It sounds like a lot of you guys have gotten there with arcade games.
I don't think I'll ever buy a Dragon's Lair, a Golden Axe, or a Teenage Mutant Ninja Turtles. All those games have nostalgia for me. Dragon's Lair is my true grail game, the one I wanted since the mid 80s back when I thought the idea of having an arcade for home use was insane in itself. But I know that if I buy one, I'll master it in a week or two and then it will sit. That would probably go a long way in killing the drive for me. Donkey Kong was my other grail game and I bought one (paid way too much probably), but I don't regret it because I play it a lot (especially since I can swap DK Jr. in there.) That experience fuels my drive. But I'm more about playing the games than restoring them so I'm just patiently waiting for the next game to show up.
I'm sure it's totally different for the guys who like restoration more than playing the games, and for the guys who make a living off of games. It is cool that everyone sort of co-exists and feeds off each other though. I'd rather pay $1000 for a mint game than $100 for a game I have to fix up.
Maybe I should by that Dragon's Lair though. Hmmmmmmm.
