Graphics creation for games?
hvs: Which tool you use to design your graphics won't mean anything if you don't have some artistic ability.  I speak from experience.  That said, if you decide to go 2-D, I would highly recommend a vector graphics editor like Inkscape or Adobe Illustrator.  I would argue that vector-based drawing, especially for the less experienced artist, is easier than bitmap drawing.As recommended by J_McQuade, toss some images together at first and really focus on the actual code instead.  Once the infrastructure is there, the images can easily be replaced.
