Aether

I've decided on the idea of my RTS. It'll probably be called Aether, and be made in either Spring RTS or the Starcraft II level editor, which both look really powerful and user-friendly and AWESOME and all that.

I'll have to see which one is more powerful, user-friendly, etc.

Each element (not periodic table elements, elements from alchemy) has a different bonus on the units and a different focus. You start with a single wizard, who can infuse Essence Springs with one of the elements you chose in the menu (the more elements you have, the weaker each will be) and once it is infused it can train units of the element. Pretty much, like most other RTS games, the idea is to either infuse all of the Essence Springs on the map or kill all the enemies' units. Whichever the player thinks will be more fun/challenging.
Your wizard regenerates.
