I'd love to have my collection full of titles like Earthbound and Panzer Dragoon Saga. But our budgets limit many of us. We can't all own a Magnavox Odyssey and Neo Geo AES. (And this is also why I don't have all my games complete in original boxes, I buy them to play them)
I'm not talking about just the most rare and prestigous games or anything though, I'm just saying it's better to have a purpose to your collection, y'know? If you love video games, and are buying video games, doesn't it make more sense top buy games that actually interest you, instead of like, 30 Pong clones that will just sit on a shelf and collect dust because they're rare and serve almost no purpose beyond historical curiousity?
You mentioned the Magnavox Odyssey... how many people who own one these days ever actually play the thing, or have a real fondness for even a single game released for it?
No, I wouldn't own 30 pong clones. I own one, because I'm really into the history of gaming (I own a few books on it, too), and having 1 lets me have a piece of that history. But having 30, yeah, that's overkill. I also don't buy 2 of the same game (unless there's also a handheld version and I want it on the go). To me, buying 2 of the same game is a waste of money that I could have spent on a game I don't already own, and 30 Pong clones falls into that same line of thinking.
However I would ABSOLUTELY LOVE to own a Magnavox Odyssey. Who wouldn't want to own the first console ever made? That's like owning the first car ever made or the first t.v. model ever made. That's just cool.
And while a focused library looks cool, it doesn't do much for me for playability. Yes, I'm a game collector, but I'm not the type that collects them just to show them off. I collect to play them. And as a result, I want a nice, varied collection to play. I might feel like a deep RPG one day, but then after beating it I might be sick of that and want to play a mindless button-masher. Or maybe I'm in the mood for a quick racing game, or a fighting game against a buddy. Maybe I want to beat my high score at Pin-Bot another day. Variety is the spice of life.
