In the vein of How about 2d6? I was recently reminded of the Traveller variants that are not based on a Science Fiction setting.
All I knew was games such as Mercator. It’s a free game by Paul Elliott:
MERCATOR is a Roman Empire setting for Classic Traveller. Marc Miller has read it and given it his seal of approval!
Low Tech Weapons provides you with a huge number of new melee weapons that can be added without fuss directly into your Cepheus Engine or 2D6-based SF RPG.
Fast Magic offers a complete, improvisational magic system.
As it turns out, Zozer games is Paul Elliott, so Mercator comes from the same source. The Cepheus Engine is by Jason “Flynn” Kemp via Samardan Press.
Another 2d6 fantasy game might be Fenris but when you start skimming it, it looks a lot more like a d20 system with the d20 replaced by 2d6. Just to give you an example, attributes are still 3d6. There are character levels and hit dice and all the things we know and love from D&D variants, so I’d say this is not a game in the Traveller vein.
