Right, I've been to the supermarket, I've cleared out my weekend and I have my idea, all set and ready to go. My entry will be a cross between an RTS and a Sim style game, where the goal is to manage a breeding park for an endangered bird while keeping out the predators and making sure the government doesn't cut your funding.
Oh and I think my programmer art will more than make up for the retro side of the theme! I will be concentrating on fleshing out the gameplay as much as I can at the expense of art and sound, I expect to have to deal with some interesting balance issues.
I will try to keep you posted on my progress once I start coding tomorrow morning, for now I'm sorting out exactly what objects I want to make it into the game and how they will interact.
