"Inspiration is the key!"
For some reason I've got really inspired by this concept drawing. Racing game is one category I didn't tried yet, but my mind is already full with gameconcepts about "futuristic junk" upgrading systems, physics-based races and... some crisps. :P
May I ask, how far did you go in the creation of this game?
And do you happened to have more of these drawings? :)
