Do what you feel good about. If it doesn't feel good, it's time to move on. I have first hand experience and further evidence to support that women enjoy playing the games produced by id Software. I hope to do the best I can for id Software for as long as I'm with the company, be it five years, less than five years or more. If you have a good idea, make it happen.
Good ideas are a dime a dozen.
You have to do something with your idea to make it valuable. Success tends to be reserved for the doers rather than the dreamers.
