yepp, I would add really, really dense fog all the time, especially @ night. And what about wings freezing over, you know, like stalling @ 300 knots because laminar flows are gone. And yes, of course I want clear icing and the not-clear variety. Just for the effect. Then random failures, so many things could fail in planes and it's not modelled. Nothing like being killed without even seeing a con or even falling clear out of the sky without understanding the reason after an hour flying somewhere. You die and can do nothing about it and that's it, just like real, real life. It's even better than real life since you cannot feel g-forces, you have no 3D or peripherial vision, you have lag, you have warps, just GREAT.
Seriously, IMHO this sim is getting ridiculously hard and buggier and buggier. New slaped in features, mostly making things harder without adding anything to the experience of a flight sim. I thought once we're out of beta we'll get some more stable product with steady improvements but no, we get stuff slapped in and things that are obviously making the sim buggy and kills lots of flight experience (88 acks, try that for a while, U may pass on fog) are just being ignored. I joined AH since I thought this is a _flight_ sim of highest quality and not a mom-and-pop, I can drive a tank and row a boat warpy 300 people in arena french-fries franchise taht it's becoming.
again, just my personal opinion here. I'd rather not see new features for a while and the existing flight stuff solidly tuned. And then throw out lots of stuff like the weather-makes-icons-invisible into restricted places for the masochists.
