The review was written while the game was still in development.
The first hour of the game completely gives an idea of everything that will be available in the game for the next n-twenty hours. Large generated locations for battles, about a dozen variations of guns/car frames/skins (paintings) that will be given for defeating opponents, and so on in a circle. And as soon as you find your imba in the form of a body (on which the number of guns on the car depends) and guns on it, then consider the game completed, there will be no further difficulties. Running it and playing around for 20-30 minutes is fine, but drowning in it for two hours straight is clearly not the best solution.
