By interactive I mean that the wind and rain affects gameplay. You can fly up and through the clouds.
Legend of Zelda:The Windwaker had this and i bet most games where the protagonist can fly have wind-effect,
these games or levels are build around these (fun) mechanics.
Sounds like a good idea or perhaps just a gimmick?
You can turn it into a good idea, but you'll have to work hard at it.
