I have no NES games. :p Only SNES games, but actually not much. For the NES games that I "rented" on vizzed, they are the following (for now):

- Mega Man
- Duck Hunt
- Action 52 (bought it here, because it's said to be very bad, lol)
- Super Mario Bros. 3
- Gimmick!
- Mega Man 5
- Mega Man 3
- Prince of Persia
- Super Sprint
- The Legend of Zelda
- Super Mario Bros.
- Contra


I will just list my SNES games that I own in real life here too, if you don't mind.

- Super Mario All-Stars (so I have the remakes of the NES games Super Mario Bros. 1 - 3 and the original Japanese SMB2, that's called Super Mario Bros. - The Lost Levels outside of Japan.)
- Super Mario World
- Lufia II - Rise of the Sinistrals
- Breath of Fire II
- Secret of Evermore

and a few more that I actually never play, because they aren't really good (at least I think that, after playing two times or so, lol):

- Utopia
- Theme Park
- Tiny Toon Adventures: Wild & Wacky Sports
- Spider-Man and the X-Men: Arcade's Revenge

I remember having other SNES games like:

- The Legend of Zelda - A Link to the Past (one of the greatest games ever )
- Secret of Mana (also one of my favorites)
- Donkey Kong Country

So, yeah. Maybe the best games that I had for SNES are these that I haven't got anymore. That's because the console was sold when I was about 5 years old and the games that I have now are all from the next SNES that was bought online. I think that's one reason why I'm here on vizzed. I can play these games again.

Here's what I have in my NES collection (these are games that I physically own, not digital versions):

Super Mario Bros./Duck Hunt (a 2-in-1 cartridge)
Super Mario Bros. 2
Super Mario Bros. 3
Dr. Mario
Teenage Mutant Ninja Turtles
Teenage Mutant Ninja Turtles II: The Arcade Game
Teenage Mutant Ninja Turtles: Tournament Fighters
Tetris

Paperboy
Pac-Man
Marble Madness

Bomberman
Casino Kid

Yoshi

I'm not sure if I still have some of these games, but I do remember playing all of them years ago. Out of the 23 games that I have listed, I know for sure that I have 17 of them. I don't know what happened to the other 6 games, but it doesn't really matter. None of them were games that I had to have, so I'm not that worried about it. Besides, I can play them here on Vizzed if I really want to.

I have these NES games:
Super Mario Bros
Captain Skyhawk
Super Mario Bros + Duck Hunt + World Class Track Meet
Wrestlemania
Tetris (Nintendo)
