I've just started an iPhone game company, where the emphasis will be on game design and lasting fun. Good games are the ones that you think about when you're not playing.

I'm not looking for this to be too kiddy, or too adult. I need a logo I could attach to a kids matching game or a space opera RPG, without it looking too out of place. Rather than defaulting to something more neutral, I believe the answer is to add more character to the Robot. You guys however are the designers and I'm certainly open to alternate theories, in fact, I'm hoping for some.
The robot should unsurprisingly be made of stone, look at the Thing from the Fantastic 4 for my idea of the texture to be used on his surface. If you're looking for reference, you can also research golems, but that's not really the idea. I really am looking for a robot, that happens to be made of stone, so including gears and machinery may help with that image. I'd also like a font treatment of the title. I have no color requirements, except that if I need to reduce it to a greyscale or black and white version of the logo, you can still tell what's going on.
EDIT: Don't submit 4 versions with different colors. I can imagine other color schemes if it's mono or duo-tone, so don't worry about that unless it actually changes the effects.
