The general consensus was that it was a fun game but once we were driving both cars around the board running down zombies it got a bit too easy. We were killing around 10 zombies with each car per turn.
I've always thought the car was a bit too powerful. It'd be funny if you made an in-house rule where you roll a die to see if the car dies on you or runs out of gas. Imagine, trying to run through 20-30 zombies and then your car dies
