as a newcomer to this world, i know nothing about how to ride a bike, what kinds of racing and bikes there are, how to categorize track sections, how to learn a new track etc.
so, i would like to suggest that someone with good knowledge on this and mx bikes itself implement some basic tutorials for people new to the game.
this could be shown in the main menu.
i can help with some text review, video editing and other stuff, but the knowledge and structure has to come from someone else.
