You have to know the rules before you can break them. It's something that has a special meaning in games because we are a very young industry and I don't think the rules are clearly established yet.
I played games myself for years and my gut feeling was that we had reached the limit of what the rules allowed us to do. If you want to go further you have to do something different.
It is always challenging to invent new rules and new ways of doing things because you need to convince other people that it is time to leave the old paradigms and find new ones.
