Ok i am new to unity ! and i want to learn how to make my own racing mmo but i don't know anything about unity really .... i have been looking for video tutorials i found a few but they aren't really helping so could someone help me get started ? NOTE : I am 13 so i really just need basics on what to do. and i am making a racing game so i need to know how to make the track,cars and maybe avatar costomizing thanks in advance !
Welcome to the forums. An mmo racing game eh? Good luck. To start, you might want to look at this Car Tutorial
I would highly suggest you take out the mmo part of your idea. Stick with a racing game, just none of the networking. Doing a racing game is a large undertaking by itself, even more so with the networking involved in an mmo. If you finish and polish the racing game, then work on the mmo part.
