Beowulf The Hunter offers some modifications for using the Rezolution rules for playing your pulp-era miniature wargames. He writes:
First let me say, I love the Rez rules. I have been and always been luke warm on the figures/setting. My current love has been Pulp. Thus I have tried to blend the two into a fun quick paced playable game.
For those who are unfamiliar with Pulp, it is the genre of literature that takes place between the end of WWI and the start of WWII. If you have seen movies like the Rocketeer, or Indiana Jones, or Sky Captain you have seen Pulp.
The following modifications allow you to use the Rez rules to play a Strapping Hero and his Dangerous Dame against a sinister villian and his horde of mooks. There realy are no point value for characters and the creation rules are pretty free form so you could have a Villian who uses his mental powers to twart the heroes while sacrificing minions to prevent damage or a martail arts using hero with a heavy gun toting sidekick.
These rules allow for 3-10 models per player and you can have free for alls. All rules are as presented in the rulebook.
Heroes Among Us is a pay-what-you-want game for quick play superhero skirmishes.
Mike Fischer offers a set of miniature rules called To A Pulp (nice pun). He writes
Pulp gaming, in which each player controls a character or faction from a 1930’s pulp thriller, is growing in popularity. Such games combine the visual appeal of miniatures gaming with aspects of role-playing games, allowing the players to control the actions of tough private eyes, seemingly-helpless dames, brave explorers, and all the rest. I wrote these rules mostly for my own amusement.
The rules are made for simplicity and fast play. The game is meant for use with miniatures, but you can download a set of paper minis for free (see Section XI). All you have to provide is a few six-sided (d6) and ten-sided (d10) dice. The game is meant for two or more players, but it can be used for solo gaming as well.
