A petition? Is it not clear enough since...I can remember that Microsoft absolutely don't care what 'serious simmers' think? They are just the company that to date has had the money and capability to turn out the 'best' simulator. The people making Flight are just doing what they're told and feeling grateful they have a job...

Why don't you send a petition to the enthusiastic people currently making alternative flightsims to FS who actually care about what they are doing and get them to improve their product? They need the money and customers and they may actually give a damn what simmers think   

Or get on the line to developers and have them make addons that fill in the gaps in FSX for serious simmers - a serious simmer surely doesn't need an even better graphic engine'which todays computers can't handle or to lose the use of all their addons in order to enjoy 'serious simming - which is what a groundbreaking utopian ideal replacement of FSX would probably bring... no?
