I'm ambivalent. I like the idea of having weather generation - particularly pressure, cieling, visability, and wind changes as in previous versions of FS.
However, I think that having FS "recreate" the exact phenomena encountered when flying into a cold/warm front is a bit beyond the scope of any flight simulator, especially one intended for recreation.
I think Microsoft may have "created a monster" with the phrase, "as real as it gets." Being a simulator, and a recreationally oriented one at that, there is no way possible for that statement to be true. Yet, the customers seem to expect it.
If you want realism, go take a flying lesson. FS will never be a substitute for the real thing.
