Wicked Fantasy Factory

Wicked Fantasy Factory was Goodman Games attempt to crank your D&D game up to 11. These were the selling points:

• E-Z stat blocks, formatted to put the important combat statistics at your fingertips
• Finishing moves, with rules to make characters more heroic
• Mooks and big bosses, with rules to make combat more dramatic
• Over-the-top action, for adventures that don't slow down!

0-3 were written for 3.5. They have an over-the-top action aesthetic that is fantastic. Temple of Blood was a teaser that takes place in the sewers. Rumble in the Wizard's Tower sees the adventurers attack a fortress in the middle of the city to prevent a war. It also features a time being and the D&D equivalent of bullet time. In Against the Iron Giant they must race towards a colossal moving fortress and stop the mad cleric of a forgotten mechanical god. Throwdown with the Arm-Ripper, well the name kind of says it all. All of the adventures are formulaic. The mook monster stats are basically the equivalent of 4E minions, and I enjoyed using them when I ran the Temple of Blood. 

As you can see from the cover art, A Fistful of Zinjas is a different beast entirely. Unlike the others, it's statted out for 4E. The book and adventure has an extremely anime-esque style. If that's what you're looking for in your game, I recommend it, but personally I preferred the style of 0-3.

I'm currently running a modified version of Arm-Ripper for my 5E group. It's been really easy to convert. I think adventures 0-3 would be a great way to kick off a campaign. These adventures are relatively inexpensive and if you're looking for something a little different, give them a shot.
