So, I found a Sega Dreamcast at a garage sale for $3. Did I just win?

I went garage sailing with my wife today, and found a Dreamcast in a bin with some other stuff. I asked the owners how much for the Sega Dreamcast, and they responded with, "The what?"

They told me to make an offer, so I figured I'd completely low-ball them (since I was just curious- I had very little intention of actually buying it, as I have neither the time nor the money for video games these days) so I said $2. They countered with $3.

Sold!

It came with a power cord (no video cord, unfortunately), three controllers, and a memory card. No games. I've never owned a Dreamcast, so I really don't know much of anything about it (though I know that everyone that I've talked to that owned one says it was the greatest system they ever owned).

I guess my question is- should I keep it and buy some games (and a video cord)? Or should I just sell it for far more than I paid for it? I have very little time for video games these days so I'm usually very hesitant to spend money on them (hence why I low-balled the seller- I wasn't planning on spending more than like $10 today so I wasn't expecting to wind up with a Dreamcast!).

Any opinions would be greatly appreciated!
