Next Car Game is pre-alpha at the moment, but I have played it quite a bit and I haven't found any bugs. The developers, Bugbear, are seemingly very thorough. Next Car Game is a racing game (there is also a derby) and it is based around trashing your, and other people's cars. There are 3 racetracks, one on gravel, one on tarmac, and a figure-of-eight though the tarmac one I find much easier. For each racetrack you can choose roughly how many opponents you want. There is also a Derby, where you win by being the last one standing (or driving), on the derby you can also choose how many opponents you have. The damage is very realistic, there is a damage thingy at the bottom left corner, which tells you how damaged your car is, and the damage on your car is............... quite fun. You currently have only 3 different cars, American (which is faster), American Sedan or European. the pictures above show the European car, which I prefer. In the Garage, which is where you start off, you choose which race or derby you want to do, and your car. You can change parts of your car by clicking on this curvy arrow thing. You can also change your paint job.
The parts menu.
When I got the game on Steam I got a 'extra' game with it, a... Sandbox(ish) version of NCG (Next Car Game). You drive around, and no matter how badly damaged your car gets, you never 'die'. Also, you can fire things at other cars! I will post some screenshots soon.
