Pretty damn annoing if theres any kind of wind, but if the wind doesn't change directions it's not a problem.
If there isn't wind at all its like the most enjoyable toy in the world. Like if you never played inside buildings.
I was once in one incomplete construction site which had 5 floors, it was like heaven there was all the boxes and expensive pipes and junk
ready to be our coverspots. Had really fun with my friends there couple years ago.
SA1 isn't the best or the worst. I bought it because it looked cool and it had a reasonable price in the market, I'm pretty satisfied.
