In the last couple of years, I've grown more accustomed to the idea of selling games back to stores or just renting them through GameFly (like Netflix for games) and never owning them in the first place. Occasionally, though, a game will be such a classic that it has to stay in my possession, and I have no problem shelling out the additional cash to buy a game for keeps. It's not that I necessarily plan on replaying the game - going back to a game is something I very rarely do - but it's more like I'm keeping it in the family. I still have all my old video game systems, like my NES and Super NES, sitting in a closet, too. In the same way my mom has amassed a library that's too broad for a house full of bookshelves, I'm building a video game library for my family's posterity. You laugh now, but I'll be the super-cool dad with the super-cool kid who's raised on the original Super Mario Bros. sometime around 2020 or 2025. In the last year or so I've really only played two games that I intend to make part of the library. But beyond that, there's tons of great games that I hope to play with my eventual family, like pretty much any Mario or Zelda game, Donkey Kong Country, Chrono Trigger (man, what a fantastic game, even today), Mario Kart, Metal Gear Solid, and a whole stack of PC games that won't be playable 10 or 15 years from now.So, gamers, what's in your library for your kids?
