It should start from Kart, till F1, or Indy, Nascar… The choosing during the driver life, will make the end result. Make this with a no end option. The driver could create a family, and a new driver… I think the racing fans in all the wolrd would love it!
And, please, use the same texture and graphics of GameDevTycoon!
I would love to play it. I recommend taking GPS approach, but with more focus on racer instead of car.
My data shows that many people loved GPS, but complained about not enough focus on drivers and teams.
I think a game of this kind should be focused more in career than in racing. I mean, races don’t need be so realistic as F1, GRID, etc…The races could be with engine of old games and AI of actual games, with a simple gameplay.
The lowest level disponible should be Formula 3. I say it cause in Formula 3 you already meet many kinds of Formulae, and even another ones of same level, as GP-3, Formula E…
For create lower categories than this one, the game could have a editor available. And for all what I told, you don’t need to make a AAA game. A simple game can have all those resources.
