This was just something I had been thinking for a while now, seems like a fun idea for people who ever play singleplayer (maybe not many do frequently. I think it would make singleplayer more interesting.
EDIT: How expand on this idea a little more, I decided I could talk about it a little bit more, be more specific. Well to start off, it's just obvious to most that this won't affect everyone's time on the game, meaning that this new option shouldn't change anyones' moral. With that out of the way, I might as well get a little more technical with things. I screenied the stage select screen, and added some boxes and stuff to show what I might add if I was Omar.
First, I would move the continue button the Normal Game/Practice Game up, just so everything could be in line.
Then, I'd put the options in the following:
Red box: Number of cars.
Blue box: fixing/no fixing
Green box: [certain car] only game option. This changes according to which car the player selected.
White box: Number of laps (simple enough, right?)
Basically that's what I would have done, I tried to keep it as simple as possbile. Of course, I was prefect with alignment myself, so of course it would look neater than it does in my edited picture.
Open for feed back. Thanks for reading!
