There is no quality of "buisness" that is intrinsic to things commonly marketed. In fact, the quality of "buisness" is inside the act of marketing a thing, not in the thing. In short, video games aren't buisness, but it is true that many make a buisness out of video games. The quality of art lies in the aesthetics and intent of a thing, the meaning it is to convey and the method it employs to do so. Thus, a video game can be art if the designer goes about it in a way suitable of art. On a side not, alot of what we call art is also used to make money; so being a product does not prevent a thing from having artistic merits.
I enjoy studying advanced mathematics as a hobby, I do not have a career in mathematics. Learning sheaf cohomolgy was extremely difficult, and very stressful; yet I found it to be rewarding. This also required working through examples until I couldn't go any further, at which point I checked the solution from a book; this is analogus to drawing a picture, then asking someone to help me colour it. If I attend a seminar and ask someone to comment on something I'm thinking of does this make what I do no longer a hobby since others would be involved? Also, entertainment and pleasure are different; one can find pleasure in a difficult achievement that was in no way entertaining.
The development of the game is the fundamental act of game creation, not resource making. A bunch of people making resources for a game are not making a game. If I'm making a game and need a sprite, which I can't make myself, to get the right feel, there is nothing wrong with asking for help since getting the right feel is what I am concerned with. In short, my view would be that the putting together of resources into a game is what people see as "making a game", therefore having others make resources isn't problematic. Consider that we are all using programs written by others to make our games, should people have to code they're own engines; seems hard to except it on the grounds that most of us don't have the talent to do so.
Personally, I think there are two classes of people(probably more) that ask for resources. The first, who I consider acceptable, are those that do so only to help fulfil their vision of what they want. The second, who fail to satisfy the ideas I expressed above, are those that tend to generate half completed ill thought out noxious amalgams of things they thought would be cool. I don't think the second class of peole should even be considered as developing a game, instead they seem to be doing what they do because they think that the result will be a great success...kinda like someone working on the Hodge Conjecture when they only know calculus, except there's no million dollar prize here
