Mobsters is a set of roleplaying rules for 1920s gangsters. It’s a well-done and complete game.
The Farland Mass Combat System is designed to help role players resolve large scale conflicts. There’s also a great — and free — program to help you do so.
Edgar Rice Burroughs’ Barsoom novels are among my favorite guilty pleasures. Sean K. Reynolds has a page with material, including monster and character profiles from his d20 Barsoon campaign.
Ars Magica is a role playing game set in Mythic Europe — nominally 1220 AD, but a land inhabited by faeries, daemon and other magical creatures. Its a great game that I’ve enjoyed playing over the years.
Ars Magica set the benchmark for magic in fantasy roleplaying. It pioneered the storytelling style of roleplaying that has become so popular today. Its setting, Mythic Europe, sparked the imaginations of fantasy fans and history enthusiasts alike. The 272-page fourth edition introduced improved systems in several key areas such as combat, character advancement, and covenant generation. This version of the game retained and improved upon Ars Magica’s powerful and flexible magic system – widely regarded as the best rules for magic in all of gaming.
The Dick Tracy RPG brings the classic comic book detective to life. When I was a kid, my dentist had a couple of books with Chester Gould’s complete Dick Tracy strips, and I used to look forward to going to the dentist twice a year so I could read them.
In this RPG system you create characters eight attributes, skills and advantages / disadvantages. Action is resolved with a 2d6+attribute+skill versus difficulty system. Tasks are rated according to a five point difficulty level. The system also has stats for characters such as BB Eyes, Breathless Mahoney, Flattop, and of course, Dick Tracy.
I’ve often thought that these wonderful characters would make great miniatures.
