Sooooooo...I was recently thinking back of this really weird strategy game that I played when I was young (but I think I never even beat the first level).
Basically I think you had an island in the sky, you could make bridges for your units to cross. You could make some kind of a turret that sent egglike machines with helicopter-rotors to the enemy. The thing I remember most is that you could build some kind of a sacrificial altar. The priest would go there and sing:
'For the wind...For the Rain...For the Sun...' Then something happened and he said 'It is done!'.
That's basically all I remember. It's been bothering me for the last days that I can't remember what it was (and I'm very sorry my description really sucks), but I hope one of you can help me!
The whole flying island and the alters with people praying sort of reminds me of Act Raiser on SNES but it probably isnt that since it was more a side scroller with rather minimal sim gameplay combiend into it.
