Yeah, they are, but really, who still has an NES (not including me), and can still play or find the original games? If you DON'T already have them, then it takes forever to find them, not even accounting that they will be at a reasonable price.

Not only that, there's much maintenence to be done with an NES: you have to blow in it to make sure that there is no dust (otherwise your saved information goes POOF), it sometimes messes up, no sudden movements if you do something good that took hours to do, otherwise it will glitch, etc., etc.

There are still some games that I play on the original NES, and there's nothing like nostalgia and good old light-based-laser-guns. Shoot ducks. Level 64 on Duck Hunt, mo. OMGLAZERGUNSPEWPEWPEW!

Yeah, they are better, but it's just too much of a hassle sometimes. I go for the Emulator, partially because it's free, and is more reliable than the NES (well, if your computer doesn't suck or dislikes Emulators, it's better). Then again, there's the illegal part to consider.
