Those by far were the best. If I had the money and space I would get a collection like the Angry Video Game Nerd has. I miss the NES days.
I think many of us are blinded a little by nostalgia. Yes, Nintendo brought us some iconic games like Mario, Zelda, Castlevania, etc etc, but the fact is that out of the approximately 708 NES games that were released, honestly there were more bad than good, but that's the deal with basically all these old systems. For every Legend of Zelda and Super Mario 3, there were 3 Milon's Secret Castle, WWF Wrestlemania, Ghostbusters, and Silver Surfer.
Still, if you want your nostalgia fix there's always the virtual console on the Wii/Wii U, or if you want to be more frugal there's always emulators, which can be handy for playing rare games or others that didn't make it over here from Japan (which there are a LOT of.)
