Using that logic, you could say that making a game in C2 is not actual game-making, because you are using code someone else made.
Not quite. The same could be said about all high level and OOP languages with yer logic then. Just for an example, C2 did NOT make a main menu system for me, that logic is up to me, and believe me, is not a easy task to make a RPG main menu. Side view battle system, C2 did not do this for me, it offered me a great canvas to work with, not the logic itself. Both these elements, are two of the hardest to code you will come across.
Like I said before; I am not against the market place itself, since I understand art is not something you can just learn. I know this, I have tried to make sprites for characters and for me is no use, I just do not have it in me, all else I can do. How I feel against templates is personal I guess, I just do not like it and do not condone it. But as long as this does not ruin this place, I could ignore it.
