I'm mainly thinking of online dogfight servers. I think coops or offline play will show somewhat different results. If you think that there is enough interest, feel free to open a poll for those.
Please focus on important aspects, I know the ground textures are very unrealistic, but then this has very little effect on how the game plays.
If you state "other", please give a comment.
What is unrealistic? Rules like no killstealing, shouldershooting and vulching. But that is a neverending discussion.
Another unrealistic thing is the choice of planes for Blue and Red. Shooting down a Mustang with your P-47 for instance. Or a dogfight between two Bf-109's at Midway.
But it has been a few months ago since I played online. I am a 95% offliner.
I voted player behaviour, to further clarify that I mean:
1. Ramming enemy planes due to poor, careless decisions
2. Forcing head-on's
3. "Tunnel vision", "Mig madness", "target fixation" - note I'm not talking about regular examples here but those when they still follow you in their freakin parachute and shooting at you with the gun over your base
4. Mindless shoulder-shooting, you think that's realistic? Wonder who would have the balls to shoot over their squadmates IRL...
5. Overall complete lack of just a little attention in managing virtual space, things are already uncomparably much simpler than IRL yet some people are...I don't know, maybe they are just ******ed
Other than that, some errors in flight and damage modelling do allow bad player behaviour and are IMO a big shadow on all FM/DM debates...
