New Game Project

I've just started on a small game project on the side. Its a Turn-Based Hex Strategy Game. I'm logging the hours spent on development, along with any particular design insights, so I can see how much work ends up going into it. My goal is to get it completed in under 120 hours. (Or three full time weeks.) Can I finish it in that time? Who knows? I'll do a complete write up of the development process when its finished.
