well, even though there should´t be much programming required, at least game making is a very, very complex topic. You just can´t handle certain things without getting in detail. (like tiling of a background for example. you just have to do it even you can put 12000x12000 pictures into C2)
Everyone who wants to make a good game and is really interested in making a game that can compete with others, is in need to get himself deeper and deeper into the topic.
C2 in his main functionalities is just the entry-gate I think.
