[quote name='blaine878']I usually sell my games, unless I really enjoyed it. If I know I'm going to play it again within a year, I don't sell it. But if I beat it once and don't want to do it again any time soon, I just sell it. If I had a game that I didn't like, was awful or full of glitches, or was just too easy, I sometimes sell it before I beat it.[/QUOTE]
That pretty much sums up my style.
[quote name='TooMuchCoolness']The answer is simple. Keep the great AAA titles and throw/trade/sell the mediocre, average, below average games.[/QUOTE]
The problem with your approach is that AAA get re-released. Why keep your copy of SMB3 on NES when you can probably find it on a compilation disc sometime in the future? (Well, Nintendo USED to do that - i.e. Super Mario All-Stars on SNES - but with digital dist., they tend to really stick us with the premium, per-title fees).
Basically, the hottest titles of today will be repackaged and sold tomorrow. Trust me, your kids WILL hear of your old games... as re-releases sold via digital dist. or compilation.
The compatibility probs bother me more - the idea that (as some have mentioned) the old consoles won't work with new TVs. Sure, they'll sell 3rd party adaptors to fix that... but they won't really make the game look like it used to. I think it'll look all warped on the newer TVs without proper scaling or whatnot.
Then there are the RARE games you enjoyed but were commercial flops. Squaresoft's BOUNCER, for example. EVERYONE HATED IT! But I actually enjoyed it (except for the lack of continue screen and horrifically evil end boss fight), so I know for a fact that I'll most likely never see it released again. Nor will Square likely make another fighting game like it cause everyone was so quick to hate...
Or how about Zone of the Enders on PS2? Sure, we're getting a PS3 sequel... but what if it fails? Will they ever re-release ZOE on future consoles??? Who knows???
It's a mixed bag. You'll be selling your old stuff for little money. On the other hand, space = money, too. All those boxes need to be stored properly, and they need a section of house to be stored. That's kind of a downside in and of itself. You get older and your stuff grows. Before long, "just one more box" becomes a very big problem in a cluttered house full of boxes!
One last thing: this generation marks the first time I'm completely selling off all games and accessories for a console - the 360. I love the system, it has some awesome games, but it has the reliability of dead dog. One day I'll toss the ball and it won't come back. Microsoft is only going to support it for so long (like all OS's and M$oft products), and one day, you'll be playing your fave 360 game, it'll RROD, and you won't have anyone to call but an expensive reseller hocking old 360 for a premium. Screw that scenario.
Really, the only console you can count on, for sure, is the older Nintendo stuff. The NES, for example, will likely function even after we're long dead. I don't know if Nintendo planned for their consoles to survive Nuclear Holocaust, but by god, they will.
