I'm giving it a 70.
Immersion-enhancing features: I'm almost completely satisfied with the overall graphics quality, in terms of what needs improvement new sounds and an AA fix are in the pipeline.
Cosmetic features: No need for them. A cosmetic feature is actually an immersion enhancing feature that's been taken too far, usually to the detriment of other aspects of the sim. Graphics and sounds are important to create immersion in a realistic manner, not movie-like effects in an arbitrary one.
In other words, i like pretty pictures too but i don't consider graphics and sounds alone to be the most important part of it: on their own they would only give us an arcade game with aircraft, not a combat flight sim.
Under the wrapping (the important, yet easy to notice parts): The aircraft fly in a believable manner and the damage model is well researched, detailed and progressive (fires spreading, secondary failures, etc). Bugs exist that need to be fixed and some tweaking is needed, we've got some already in previous patches so i'm optimistic the rest will come.
The meat of it all: This is actually things that most people fail to notice, or completely lack the imagination to foresee what can be done with them. The amount and quality of stuff that can be done with the support for scripting in missions is insane, not to mention the support for directly integrating custom-made modules in the sim with their own interface. Sadly, many are too hung up on carrying over their old IL2 habits and miss these capabilities, or confuse legitimate features for bugs, but we'll gradually get there.
Long story short, i would give it an 80 if not for the existence of bugs that affect actual gameplay, that is flying the planes and doing what they are supposed to be doing, otherwise it runs pretty enough and stable on my two year old PC already, it's the gameplay issues that i'm after currently.
These bugs would drop my rating between 65-70 but i'm cutting some slack and giving it a 70 because of all the cool stuff that most people routinely fail to notice while they are focusing on issues that have already been done to death
