Lately, I've been cloning games in C# with XNA (ex: tetris, bejeweled, and a few others) for the purposes of learning. (Note that there isn't an extreme amount of polish as I'm doing this simply as an exercise). Now that I have a basic understanding of how this stuff works I'd like to work on more advanced projects. One that comes to mind (but may be slightly overboard for my current programming ability) is Final Fantasy Tactics. The problem with this is I have absolutely no idea how I would ever get textures (or heck, music or sound) for more advanced projects like these (which is the only thing currently stopping me).
Before you say - "oh, just go to X website and download 7 images from there, and go to Y website and get 4 images from there" - I want to mention that these will not be polished products. This is an exercise so if I have to hunt down images and whatnot then it simply ruins the entire point.
Any ideas?
(Note: I'm comfortable with C++, C# and XNA stuff, currently learning AS3 and Java in school, so if I should devote my time toward something else as a game programmer, I'm open to those suggestions as well).
