I did the MCC course on a 737-200 simulator (as per the 'clockwork' 737 sims above), it was all handflown and it was a total hoot. Just basic night graphics which is irrelevant for an MCC, but may detract from what you maybe expecting.
A session goes quickly, to get the most out of it you should ensure you get a small amount of basic information up front to give you time to memorize it (basically flap/speed/power/pitch settings), otherwise you may end up a bit frustrated.
I won't spoil the fun of discovery or try and set any expectation with regard to ease or difficulty. Needless to say regardless of the age of the sim I experienced, it was very immersive, I was certainly sucked in and I'm sure you will certainly get a feel for what it is like to fly a jet airliner.
