proposal for a new video game

You can think of any game, let's say a car racing game as an example:
1)Title
can be creative and attractive
~ ie Cool Car

2)Type of game and rationale
~ then describe the video game
maybe there are a few games available:+ rationale
--> car racing competition(car,motor cycle)==> win the competition
--> car designing==> develop creativity and mechanic knowledge
--> run a car company etc==> learn how to do a business

3)Storyline and main character, rationale
--> assuming you are a normal guy or girl and hope to try out sth extraordinary and you are a car lover and wish to do sth related to cars
--> main character: can choose among various characters: kind,brave,strong, weak....
rationale: develop one's character through the game

4)supporting characters, rationale
--> friends competing with you
--> bad guys
--> parents,girl friends etc
rationale:establish good relations with people

5)Target market
--> any you want: teenagers, adults...

hope it'll be useful to you~
