Here's a good subject, "Bad NES games you love to play".

Dance Aerobics!!!111! Gotta love the legwarmers.
MC Kids is pretty fun. It seems like it should be bad, but I think it's a pretty decent game. (Maybe that goes in a different category.)
I <3 Pinball. A lot. Again, I don't know that the game is bad, but I have an affection for it that seems unwarranted.

I'll look through my collection and see if I can come up with some other answers.

I seem to like Gilligans Island and Nightmare on Elm Street. Probably because I played tham alot as a kid.

I play Cheetamen II a lot...I have so many other great games to play, but that one always gets me for kicks...my first thought is always 'Why can't you duck you bastard!'

McKids is pretty much a poormans Mario, but I really like the absolute craziness of all of the MCDonalds games.

Simpsons game for the NES I really love, I don't know if everyone thinks they're bad but I heard alot of negative comments about them.

Contra Force gets hate because it's not a "real" Contra game, and also because it's so short and very easy - but I love the hell out of it. I mean, one level is jumping from plane to plane from the tips of their wings. What's not to love! I also like Anticipation because the music is so damned catchy, and Tom Sawyer just for level two where it becomes a twisted shoot-em-up that dares to have you, instead of something cool like the Vic Viper, piloting a kid on a raft.

Friday the 13th. It has some serious suck attached to it, but at the same time possesses a mysterious charm.

I'm with ya there on Dynowarz. I also like Astyanax and Kung Fu Heros.

Yeah, Cheetahmen II rules... I also play T&C a lot for the nostalgia kick and about 50 other "bad" NES games off and on.

There was a time span of roughly 6 months when my best friend and I devoted an obscene amount of time to playing Jackie Chans's Action Kung-Fu. Not a bad game by any means, but definitely a childhood deviant obsession.

I always liked Fun House even though I know it's a sucky game.

I've always had a soft spot for Bad Street Brawler. It really seems like it's goofy on purpose, and it is somewhat fast paced and interesting. I've always enjoyed playing it anyway.

I felt cheated by Fun House when I played it. I was expecting messy stunts and a romp through an obstacle course, just like Double Dare from which it was ripped. I was sorely disappointed, it just wound up being some kid on roller skates for the whole game. It wasn't a bad experience, I played it for a while....but just a bait-and-switch

I've been obsessed with nes Ghosts n Goblins for years now. I frekin love this horrible terrible game. I'm pretty good at killing the demons but god it's a hard game.

I stick to Legend of Kage. Limited graphics, repeated soundtrack annoying sound effects.. but i love it.

TheHarvestDude

I'll second Friday the 13th.. One of my favorites even.. I just really like it

I like Golf.

That's about as plain as it gets.

Same course over and over, extremely limited sounds, no music, no yardage. It's great.

Tecmo World Wrestling, Rescue Embassy Mission, Tiger Heli, Operation Wolf

Solar Jetman

Super Mario Bros. 3

^^^ I love Tiger Heli.  If you have MAME try the arcade version and play it with better graphics.

Mario 3, Solar Jetman and Operation Wolf are all _good_ games guys

Op Wolf is a really super 8-bit adaptation of the arcade, there's constant action, lots to do, plus it's a zapper game. Compare it to Duck Hunt. Only problem is using grenades :/

Kung-fu

I must be crazy, because I like almost every game listed here so far. Yes, even Cheetahmen 2. : ) To add to that, I love playing some Action 52. It's like playing Atari 2600 hundred games, but you never change cartridges! 2-player + beer = great fun, too.

Hey, don´t mess with TWW

I played (a lot) Infant School, is about a little girl that must escape from a school invaded by... lava?, then when she reach the top floor she rises to an... UFO? (yeah!, pretty sure it´s an UFO), next she grew up, and so on. Give a try, it´s a bad game, with some angel inside.

Maybe the game doesn´t sounds familiar, because cames in pirates multicarts, but the Japanese tittle is: Urusei Yatsura: Lum No Wedding Bell
