I coded this in 48 hours for the RPI GameJam competition, which ended today. It’s actually based on a board game that I’m working on and personally feel is far superior, but it’s worth checking out anyway – if anything, it’ll give you a good introduction to the wonderful board game that is to come.
(Edit: The game referenced is Infinitron.)
It’s a two player hot-seat (one computer) game that’s probably going to be confusing at first. However, there is an in-game help that should give you a few pointers to get you started. The basic gist is as follows: research units and then* build them* to capture cities to gain points (gained at the beginning of your turn) and increase your unit cap. Researching and building units costs points. When you capture a city, you can create and shape the terrain around the city, but only once. Begin your turn with one of your units on the enemy capital to win the game.
