CEM aside - can FSX really simulate the flight model that great? I haven't been a fan of the civil flight sims and find them boring but the videos I usually see are... questionable. Most of them show flaws especially regarding complex FM e.g. stalls and spins.
So while the buttons and gauges are maybe working better - does the flightmodel really work better as well? E.g. can you do a few test runs and verify climb rate, turn rate etc?
I agree with all who said it's apples and bananas though. A warbird without weapons? Not a warbird to me. I think the damage model is at least equally important. It's like comparing a model plane to an RC one - one may look shiny and have the details but it's not experiencing all aspects of flight / fighting.
I'm not sure if CloD could ever reach that level of detail for individual - after all they don't just make plane models. Maybe they could buy rescources to make it easier but then again - it'd probably mean CloD would end up costing 400$.
