What do you think about point number five; graphics? Is graphics an important part in the next future game hit? Graphics is certainly not a priority in the social games that have been succesful so far. The beauty of many hit social games I feel is in that they're so easy to start to use and even my mom understands them, will AAA graphics add to that effectively (since it's so expensive)?
Disclaimer: I'm not a gamer or games programmer. But it seems to me that "good" graphics are not just about beauty, but style and personality. For example, South Park animation is crude but instantly recognizable as South Park. There would be no point in converting it to Pixar-level quality except as a joke.
