I created a great scenario for conventions revolving around a penal arena. Convicted convicts are given a chance for freedom by auto-duelling in the arena. The winner gets a pardon and his freedom.
Of course, I don't do anything small, so we play at 300% of the standard Car Wars scale, using 3D, 20mm (1/72nd) cars and figures. (As opposed to the 1/2"x1" flat counters on a 1/2" grid map.) Here are some pics of a recent match.
The Florida Memorial Penal Arena
The line-up of available vehicles.
The battle has begun.
More battle goodness.
Sedans with rockets and MG's. Each vehicle is mounted on a 1 1/2" x 3" foam core base. Makes movement a lot easier with the turning key. (see below)
Pickups with turreted Mini-guns and MG's on the hood.
Sedans with roof mounted HVY rockets and rocket launcher on the hood.
Sedans with a turreted recoilless rifle on the roof.
Mighty mini-vans with micro-missile launcher to the sides and an Auto-cannon on the hood.
"Look, it's Mom's taxi on steroids!"
These are the left and right turning keys (templates) that we use for the 300% game. (for scale reference, that inside 'L' shape is 3" x 6".)
