Skipped the op. Just read the title.
For me, the perfect game does everything it sets out to do very well. It's easy to learn but it's obvious to tell a skilled player from a novice. That's pretty much it. Gonna have voice acting? Do it well or not at all. Gonna have a driving section? Don't make it frustrating. Make it fun.
Do whatever your vision is without making it a chore to play and you have my vote.
