RPG-like Tech-tree
Enables an alternative RPG-like tech tree.
The tech tree is divided into four basic science branches: Engineering, Physics, Biology and Government. The basic science branches cost research points, but grant no tech applications at all.
All tech applications are in leaf technologies. This means you can wisely choose which tech apps you want for your civilization.
You can choose a deep strategy. You can choose a wide strategy. Or anything in the middle. The combinations are (almost) infinite!
