Since GameCraft was a bit of a bust for me this month, I decided to have a go at Ludum Dare for the first time so I thought I might combine the two themes. So for 'You only get one' and 'The End' I thought of making a game based on Carl Sagan's quote from The Pale Blue Dot, from Cosmos, about how Earth is "...the only home we've ever known". In the game you'd have to protect the earth (or out ability to inhabit it), from killer asteroids and comets as well as from humanity itself; global warming, nuclear war, etc.
There'd be a number of AI countries who are all looking to provide for themselves in terms of water, food and power (and oil). Your role is to prevent them going overboard and doing harm... with your space based laser!
Do you prevent them from building more fossil fuel plants?
Do you shut down their nuclear programs? Are they going to use it for cleaner power or for weapons?
Do you destroy their rockets? Are they going to launch warheads or satellites to help search for killer asteroids?
All vastly overambitious, especially as I was also using it to learn Unity. So I didn't get too much done; definitely no 'game'. But I do have a rocket that builds itself and launches, so there's that.
