Haven't read all the other answers..... I was afraid of getting biased.
The short answer is: Total Waste of Money...... for 98% of all flightsimmers.
But a great addition for the super hard core 'simulation pilot' who wants his aircraft to behave as close as the real thing and just can't scrape that last $ 40.000 together to get that second hand - sorry, pre-owned - Cub that he really wants.
I would tend to agree with the above and also TJ (also above) who resumed it quite well , I believe :
"I think you have to ask yourself what type of flying do you do? For me Accusim is most noticeable at the edges of the flightsim envelope. Stalls, aerobatics, flying outside of published limitations, poor power usage...etc. If you do a lot of short point A-B flights well within the flight envelope and recommended engine settings, it wont be quite as noticeable".
For myself, I do short hops and touch and go flying most of the time. I bought the Accusimmed B-17 and the Spitfire which I leave in my hangar until that time when I find the patience to read through the manuals from top to bottom and then try "again" to get the engines to work at least long enough for a short spin around the airport...
I guess those who really enjoy all the real stuff about checking the speed, the oil and what not are probably ex-pilots or would be real life pilots eventually...
All this being said, I think that the concept is right to start with and it all ends up being a question of choice...
If A2A ever get the Bf 109E redone and accusimed the way that the Spitfire was, will I buy it or just take the basic package... ?
The 109E being my all time favorite, I will definitely take the whole package as I'm probably more willing to spend some time understanding all of its intricacies...
Sounds a bit crazy, I know, but it is my hobby time and feel free to invest it where and as I choose...:salute:
