How many types of Blood Bowl are there? I've heard terms like 7's, 11's (standard Blood Bowl I'm guessing), Dungeon Bowl.
There's 11s, the main game. 7s the minor leagues. Dungeon Bowl, Wizard college blood bowl in dungeons. Gutter Bowl, Street Blood Bowl Blitz Bowl, which I think is Blood Bowl 6s, smaller faster game.(Only appears to be available in certain countries, the U.S.A and Germany are the only two I know of.) 7s rules will likely come out in the Death Zone Supplement. Dungeon Bowl will likely be re-released some time next year. As for the other two, that is up for debate, but I do think Gutter Bowl will make a comeback.
Wow, that's a lot. I wonder why there are so many variations of the game. How popular are these offshoots compared to the mainline Blood Bowl game?
7s and Dungeon are probably the most popular variants, but Gutter Bowl sold out when it came out, not sure if it's still as popular though.
Are the games pretty similar? How do they differ? Which ones do you like? Are these all official Games Workshop variants or community driven games?
Some are official. Dungeon and Blitz at the very least. Dungeonbowl was basically Bloodbowl: Space Hulk edition. Passageways were essentially no wider than 4 squares, meaning it was very easy for a team with many high-strength players (ogres included) to straight-up wall off the route to the endzone. Blitzball took Bloodbowl and made a street game out of it, the idea being that the game was being played in the middle of the town's market square. Unlike Dungeonbowl, Blitzbowl otherwise played on a standard-sized Bloodbowl pitch with its own quirks, much like the team-specific ones.
