I love NES games. The best thing about them is that you can find them so very cheap. I've got quite a collection building up, and I'm beginning to sort it out on IGN.

I'm having a little trouble finding all of the games in the database, so I'm going manually one by one putting them in. I did my first 100 NES games and a few of my SNES if you want to check out what NES games I liked and disliked.

And I will say this:

Double Dragon II has the best NES final battle ever.
