This is a game that was made back in 1997, and is now one of the most chalangeing (and sadly obscure) RTS games in gaming history.
Ther is a plot, but its extreamly veuge. this is it in my own words.
Welcome to the planet of nimbus: a litraly war torn world with the nimbian race living on islands flouting in the atmousphere. this is causes by the war of the planets 3 gods of Wind, Rain, and Thunder (known as "The Furries"). Under your command, you must battle you fellow nimbians and sacrifice your enemies High Preist to the furries so that they will bestow your people with new weapons to further crush your enemies.
There is no end to the fighting, there is no peace, and no matter how hard you try, theres not a thing you can do to stop the madness.
Although I mentioned fake gods and sactifices, the game never gos super religous into it. (I never really think about it.)
it is an awesome game... but google it to find the home site. (out of fear of a modsnip) This game is abandonware from activision and the now "sunk" Titanic Entertainment companies. And is now in the gentle hands of a small, but caring community.
