I bought an SNES the day it launched, and had a massive collection of games for it. But back in those days, I would sell my old systems to get new ones. I think I sold my SNES and Genesis for the Saturn and Playstation.
Oh how I regretted getting rid of them.
I did manage to find an SNES Model 2 mint-in-box for $20 within the last year or so and I've started building a new collection since. Same with the Genesis - I got a new-in-box Genesis Model 3 for $20 and now I'm collecting games for it. Oddly enough the games I tend to buy now are the games I never owned as a kid, aside from the few really stand-out games I loved.
I've also recently obtained yet ANOTHER N64. Got one at launch, traded it in toward Dreamcast, bought a Gold Edition N64, sold it, and now I'm on my 3rd and trying to rebuild that collection.
I have an original NES console on the way too. That was the system I regret selling most, because I must've had close to 50 games for it...but alas I would not have had my SNES.
Guess it all comes full circle. Now that I'm an adult I'm recapturing my youth and those dumb trades and sales of my old systems.
Now all I need is to find a mint, working Atari 7800...muhuhahaha.
Ahem. Sorry for the long winded post.
