I would disagree slightly, but this is a subjective opinion as it all depends on what engine you’re using and what type of game it is :). Some are mostly art, others are mostly programming.
Personally, I’d rather spend my time enjoying doing what I’m actually good at. I doubt if my occupation was art/modeling I’d be spending time in a Java Gaming forum – it would likely be some where else (IE: a game engine forum that has programming-via-drag-and-drop, for example). I’m not saying the artist wouldn’t be here, but the common thing that ties us together here is programming.
Recreating an asset, either art or sound, would be a gigantic waste of time for me, and of course I’m going to end up with my own bits-n-pieces. But if I can manage for things to be reasonably good looking and not go broke in the process – I’m all for it.
