I've been doing a weekly blog series called "Three Hexes" - simple campaign starters meant to show that a GM doesn't have to create a huge world in order to start an interesting campaign.
This week's entry might be of interest to some OSR folks as it's based on the scenario "Sturmgeschütz and Sorcery", an article from Strategic Review Vol 1, No. 5. That's the game where Gary put a German WW2 infantry patrol into a fantasy world against a troop of evil creatures.
My idea - what if it wasn't just a small scouting force - what if an entire battalion "crossed over?" How would that affect the fantasy world and vice versa? So here's my Three Hex campaign starter - I hope you enjoy!
Another example is the campaign area described in the original Temple of Elemental Evil module. It basically covers the three Greyhawk hexes centered on Hommlet, Nulb, and the Temple. It's true that the setting is well fleshed out for this one, but restricting yourself to just what is included in T1-4, it can easily be fleshed out into something else entirely through sandbox play.
For the "Sturmgeschütz and Sorcery" hexes, I think it would be great fun for the players to be fighting the Nazis; plus, what if the Nazi's form a new axis with the Goblins? The exchange of occult practices and military technology between the two factions would be terrifying.
foxroe - yep, there are many ways one could take this and run with it - imagine the Isle of Dread or the Giants of G1-3 having this thrown into it? Or the Germans finding the spaceship on White Plume Mountain? Or Acerak having his own Wehrmacht zombie battalion?
