But you have to be careful: my amateur OpenGL 3d game had problems running on half of computers, especially laptops. It's because various cards support different opengl extensions. You can't use non-power-of-two textures, can't use textures bigger than 512x512 (or other number), can't generate mipmaps automatically, can't have too big display lists.
I thought about optional DirectX renderer when running on Windows, because I've heard it's more standarized.
The non power of two issue is not a problem. Just load the texture in with padding to get it to the next power and put a texture region in that doesn't have the padding.
OpenGL is an awesome platform for those who want system portability IE minecraft, or any other indie developer who wants maximum exposure.
