Main Objective: I would ask developers to add car engines to the game. Side objective: ANY options for modifying the engine, ranging from choosing the capacity, e.g. 1.6L, 1.8L, to major modifications such as various types of engines or the ability to choose fuel, e.g. diesel, boxer, V4, V8, W16, 4 in-line, or just mentioned types of fuel, e.g. oil, gas, gasoline. I will be very grateful to the developers if they meet my request to a minimal extent.
