Originally created and released by Games Workshop in 1986, this was one of the first British roleplaying games to get any kind of traction. Previously Dragon Warriors by Dave Morris (another amazing game) had been released, but failed to really get anywhere. WFRP built on the success of Games Workshop’s tabletop battle system and setting and borrowed heavily from it. If you have played Warhammer Fantasy Battles at all, you will recognise the setting, the stats, even the combat rolls that are made.
What sets WFRP apart however is the character creation method. Your character will go through ‘professions’ to gain experience and skills that are tied to what they do. The character progresses through a number of professions as the go through the game.
The overall setting is pretty gritty, and the combat can be a bit deadly, but overall, if you like the Warhammer universe, you will most likely enjoy this game immensely.
To get the original Warhammer Fantasy Roleplay experience, try 1st or preferably 2nd edition and play through the Enemy Within campaign. The Enemy Within campaign is one of the most stand out roleplaying campaigns ever published. Warhammer 3rd edition has been released by Fantasy Flight Games
There are a number of articles about getting started with WFRP at Dice of Doom.
