Thanks everyone. There are so many flying sims out there I thought there would be a lot more ATC stuff too - especially for us that are interested.
I tried the ATC-SIM, which looks cool, but you got to remember a string of commands short cuts... and do aircraft really go fast like 250 on departure and do 140 when 12 miles final? seems not so real that way. I also thought the arc of turn would be different based on speed.
London Control looks better but seems pricey.
