It isn't often that you find an unopened, 12 year old board game in a charity shop (for £3.99, at that). And, honestly, that probably should have been a warning. Or an omen. Buffy: The Vampire Slayer The Board Game (2000) is like entering the Hellmouth.
The physical elements of the game are deceptively simple. There's a board with a rectangular track on it, with 8 locations (High School, The Abandoned Warehouse, The Library...) spread evenly around the board. There are also three sets of cards: colour cards (8), character cards (8) and "Fate" cards (some amount). Finally, there are 8 crappy little plastic coloured doohickies that look like they fell out of Sorry.
The game pits the vampires versus the humans. There are 3 of the former and 5 of the latter, each represented by one of the character cards. The objective of the game is to eradicate the enemy, and the winning side is the last one standing. The trick is that the game is conducted in a state of existential chaos: nobody knows who is playing who. Or even what game piece they are.
