Killing the genre?
Last time I checked the genre seemed pretty alive to me. Black Shark 2, DCS A-10C, X-plane 10, Aerofly FS, Take on Helicopters, Strike Fighters NA, War Thunder, Falcon 4 BMS, Condor Soaring, Rise of Flight, Combat Helo soon... Hey. I even have some decent flightsims on my phone.
We never had so much choice since the late 90's! It actually feels like a new golden age if you ask me.
Don't get me wrong. I disagree with the direction they are currently taking the project, but at the same time I think it's going to be interesting watching how it evolves over the years.
If you don't like it, It's Ok. It's not a game for you. There are a lot of fantastic alternatives out there. But they are certainly not killing the genre
I agree that "killing" Flight =\= kill the genre. But, in one way that list you put up shows how dire things are:
*Let me say up front I actually have played and enjoyed all of those sims except Aerofly (still waiting for it to come state-side on steam) Warthunder (still in closed beta) and condor soaring (what the hell is that?). This isn't a "rant" but more a quick "industry overview."*
DCS Series: Shows you can make genre defining titles....if you recycle 10 year old code and shunt the development costs to government defense contracts. Also, compared to combat sims of yore, lacks dynamic campaigns.
X-plane 10: An excellent software given it's sourcing, but (IMHO) it's always been about a version behind the MSFS series in terms of graphics and sophistication, up until it's latest version. XPX does look to have a bright future though,this must be said!
Aerofly: Pretty looking, but still some steps backwards, only one time of day, and one country. Also lacks advanced systems modeling. Still great (from what I read; I plan to buy a copy) but it's simply very narrow. Basically an aircraft physics engine laid over a map of Sweden.
Take On Helis: The commercialization of a major upgrade to a ground combat sim. Fun, but still shows it's roots in a few too many areas. Painful voice acting doesn't help either.
Strike-Fighters NA: So this is the first "totally new" entry in the series in 7 or so years? ::long, deep sigh:: <NOT a series I'd use to highlight how "rosey" the flight sim genre is at the moment">
War Thunder: Is this actually going to be a sim?
Falcon 4 BMS: ...Isn't making anyone any money.
Rise of Flight: Has a community dividing price model (note: I'm fine with it, but others aren't as happy), took a long time to fix, and has no successor in the near future.
Condor Souring: Devs forgot to code engine physics and marketing team saved the day.
<JK, I've never played it, so can't really comment. Still, I doubt this changes my overall argument much>
Combat Helo: Looking forward to this programmers side-project that's been "two weeks" away for years.
Cliffs of Dover: I'm betting there's a reason this one didn't make your list, and that's all I'll say

Remember, Flight sims used to be the creme dela creme of the PC game shelf at your local big-box. We're talking a time when the "Janes" name was more lucrative than "Madden." They had cutting-edge graphics, sound, and programming. All the big pubs had a sim in the works as a tier 1 project. If the Genre was "better than ever"
Mass Effect 3 would have been sharing budget costs and manpower with
Janes Joint Strike Fighter and
World of Warcraft would be hosted in the same facility as
World of planes.
If you want to compare how the genre is doing now, the better comparison is where they are versus other titles. Heck, compare flight sims to driving sims: Imagine what a flight sim could be with with Gran Turismo 4's budget.
And let's not get started on the hardware market. (Do a search for Suncom Talon

)
Again, please understand I'm thankful for what we have, and love all my sims,but I'm showing that things aren't as great as they could/should be.
Now, if you'll all excuse me, I have a date with an angry, ugly, and sexy Russian attack 'copter

PS: Regarding the dead horse- The beatings will stop when MS improves moral. Namely by focusing on the little details, like cockpits.
