I’ve decided that my game should be about discovering ancient ruins! Gameplay will go as follows;

1) You land from space and have to build your base. You are attacked by waves of enemies coming from points around the map.

2) You have to find where the ancient ruins on that map are: the main way to do this is to randomly explore, the the enemies around the map may make this difficult. Alternatively, you can destroy all the enemy bases and then the location will be revealed to you.

3) Fog of war! The fog of war covers the whole map and will grow back unless you post sentries nearby. Sentries have a relatively long line of sight. I’ll achieve the “fog of war” effect with a large texture and a post process effect, which blackens areas you didn’t yet find, and greys out areas where the fog of war has grown back.

I’m going to do this RTS in the C&C style: a panel on the right of the screen contains the controls for building structures and units.
