Yes! Albeit FSX doesn't feature anymore the weather engine linked to Jeppesen data its seems, it keeps a product per se and Boeing-related (as Prepar3D, for example, is providing no Boeing nor Cessna as Lockheed Martin related). The boxed Gold edition of FSX, on the other hand, even second hand, is now getting to high prices
And, as far as the weather engine is concerned, it may be replaced with freewares. I personally use the FSXWX one, or FSX may also be greatly improved with the rdart78 shaders (at https://www.avsimrus.com/files.phtml?search=rdart78&sopt\_mode=or&in\_folder=85&sopt\_title=1&sopt\_desc=1&sopt\_author=1&sopt\_fname=1&sopt\_comms=1&minrating= ) and a whole series of freeware available on the Internet
