Obviously you haven\'t been down in the sewers, then you would understand that Rain would be a terrible, terrible thing.
Carefully walk around and note how often you go up and down and you soon get an idea that there are low spots that would flood out, perhaps back up water back into the city streets.
Now imagine if anyone was down there - The horrors.

There was rain in an earlier version, it is a doable thing. It was kind of odd rain though. I liked it, soothing, calming I would stand out in the rain, music off and volume turned up just to enjoy the rain.
