Brillance (2006)

You have to supply the shops of a medieval town (Brillance).
The one who can supply the most shops before sunrise (10 turns) is the winner.
The problem is that the streets are very narrow, so they get blocked of by the other players. Each round you receive an obstaclecard, with which you can obstruct your compagnions' routes. Give their carts a broken wheel, put a drunken dwarf in their way, make them crash with other players, call the guards on them etc. Obstructing your fellowplayers is one of the main mechanisms of the game and also what makes this game so fun.

Brillance combines strategy with a bit of screw-your-neighbor.
