I have an idea for a game that I'm working on now.
Basically, most of the game is spent trying to prepare your army so that they can stop the "Cycle". Throughout most of the game, you will be trying to collect resources and forming alliances so that you may have a chance to end the cycle.
Think of cycles as Bloodlines from Infinity Blade. In the last battle, I want it to be kind of RTS combat, but with "in-direct" control of your army.
The goal of the final battle is to give your plan (there will be a few different plans to be able to be used)enough time to be put into effect.
If you fail, you will begin a New Cycle. I hoping to be able to put different endings in the game (a few for losing, some for when you win).
If you win, you will be able to start a New Cycle +. (new ending, 10 extra "phases" which give you the opportunity to get new unit types/resources).
Some alliances will either give you more unit types, more ground troops (ground troops are your last defense and enemy units that get past your final blockade will deplete them), or more resources (currency that will allow you to make units during the final battle, help form some alliances, or be used to buy extras.)
