Off the top of my head?

1) River City Ransom

2) Tecmo Bowl

3)   FF1

4)  Super Dodgeball

5)

1. Mario 3 (still the greatest platformer ever)

2. Legend of Zelda

3. Dragon Quest (just so freaking addicting, playing it right now on my nexus actually)

4. Super Mario Brothers

5. Bubble Bobble (childhood favorite of mine that has stuck with me, multiplayer is a blast)

1. Ninja Gaiden

2. Mike Tyson Punch Out.

3. River City Ransom (aka Street Gangs)

4. Zelda II

5. Astyanax

Sadly, I never got to play Super Mario Bros. 3, so despite all the (well deserved, I assume) praise I cannot include it in my list:

1. Super Mario Bros.
2. The Legend of Zelda
3. Wrecking Crew
4. Ice Climber
5. Duck Hunt

1. FF1
2. Megaman2
3. Zelda I
4. Castlevania2
5, SMB

This was much too difficult. There are too many good games.

SMB2&3, MM3, Casltevania, Ninja Gaidens1-3, Kirby's Adventure, Metroid, Punch Out!!, Zelda 2, FF3, Double Dragon and on and on and on.

1. Super Mario Bros. 3
2. Kirby's Adventure
3. Ice Climbers
4. Excitebike
5. Final Fantasy III

Only five... from my favorite console of all time!? Well, here it goes:

1. The Legend of Zelda
2. Super Mario Bros
3. Mike Tyson's Punch Out
4. Bionic Commando
5. Super Mario Bros 3

Had to list more favorites...

Metroid, Super Mario Bros 2, Rygar, Mega Man 2, RC Pro Am, Contra, Kid Icarus, Ice Hockey, Metal Gear, Zelda 2: The Adventure of Link

Not gonna lie, the NES sucked.. When the SNES came out, now that was the game changer.

I knwo the feeling haha. It was hard for me to pick my top 5 (hence I filtered out mario to get a few mention of others haha)

These are probably my top five from when I was a kid.  GI Joe and Die Hard pissed me off a lot though.

I didn't fall in love with RPG's until a little while later.  Otherwise a few of those games would be in this list.
