Recently I've been making a lot of 2D art for a small platformer I'm developing (more of that can be found in my journal either by the weekend or sometime next week), and I've been using GIMP to produce all of it. I made these tileable land sprites last night in about two hours (forgot how many pixels I was working with and as a result it wasn't seamless the first try):
It was also my first attempt ever at creating sprites pixel-by-pixel, and it was well worth it, I think! I learned a lot.
For 3D stuff I've always used Blender, and its built-in UV Mapping tools for texturing and GIMP again for making those textures.
What programs do you use for your game art?
