Personally I would like to have daylight 24/7 with absolutely no rain, storm or whatever. But hey, that's just me. Don't feel bad if you like the rain.
FPS-games should focus on destruction and mayhem imo, not the weather. I'm the type of guy who couldn't care less about high quality graphics, I'm an FPS-man (as in frames per second) myself. Which also means that I will have to get the biggest and baddest computer out there to be able to play and enjoy Huxley.
