Waiting another few months to release this game may have done wonders, as it was lost in the shuffle of more anticipated releases (ie, Warcraft 2). Such a great game should never do so poorly on the market.
The game itself is simple: you control your priest, who alone can build your temple and factories. Temples provide you first unit of power, and factories research technology: from weapons to defensive towers to 'portable' power generators.
To play, you also need to build bridges. The skies are full of floating islands, from large ones of players to minute obstructions. Effective bridging is a key element of the game, but only practice can make you effective.
Strategy is surprizingly rich in a game where all units except priests and resourse gatherers are immobile. How do you counter crossbows? Thunder cannons? The gigantic Man-'o-wars? The basics of the game are learnable in a day, but you'll have fun playing for years.
