A load of old bowls
Ah the memories, although can't say I was that struck on Blood Bowl - the play area was a bit small and restricted for my taste after a little while, although some fun could also be had with the regenerating Skeleton Crew if you played it right, or of course the Chaos Dwarves.
That said many a happy day was spent at the youth centre with a few mates and Dungeon Bowl (the spin-off from Blood Bowl), especially due to adding a few boxes of dungeon floor plans and having a playing area of several square meters of corridors, rooms, traps and treasure etc.
Great fun, and sadly far too many years ago...
