The author of this topic, from the sound of it, is not a professional artist. They just want to be able to whip together some basic artwork that they can put in their game to get it running, for now, and spruce it up later. It sounds like they are not even all that great at art (they've mentioned more than once that the graphical design is not their strength). Buying the most expensive tools will not make your art any better. If I give a baby fingerpaints, the picture they make is going to look pretty much the same whether I give them some scrap paper or a $1000 canvas to paint on.
I'm not saying the author of this topic is a fingerpainting baby or something. I'm just saying that Adobe's products are for committed professionals, and there's no reason to purchase them prematurely if something else will suit your needs perfectly fine.
EDIT: And you can make very professional art in free art programs. They're usually just a little more difficult to do the more "special effects" kind of stuff with. But I mean, people paint with traditional tools with no computers at are, and that's even less convenient than a computer with free software, and that's just as professional! I've done plenty of graphic design projects for companies and stuff using tools even as simple as OpenCanvas (which is pretty much MSPaint deluxe). I'm not trying to say I'm some amazing artist, but how you use the tools is the most important part.
