I know the SNES pretty well so I will stick with that.

Here are some gutter-trash games that really stand out:

Bebe's Kids: HORRIBLE brawler that has to be seen to be believed.

Race Drivin: Amazingly bad, this game has a course you cannot even finish

Pit Fighter: The WORST game I have ever played, bar none. Utterly broken in every way.

Captain Novolin. A game where you play as a diabetic superhero and must avoid bad junk food or die. Funny, though

RapJam: Volume 1: Terrible basketball sim from the makers of Bebe's Kids.

Obitus: Abysmal D and D ripoff effort. Worst RPG on the system

Mario is Missing: Boring educational game starring luigi.

Revolution X: Laugh out loud funny! Play it even though it is bad!

Waynes World: Great game: NOT!!!

Super Noah's Ark 3D: Funny but flawed shooter by the developer who brought you Bible Games.

All of these are pretty bad. I had to suffer through all of them!
