Orbx has the best scenery, plus peopleflow technology and upcoming trees that actually drop leaves in the fall.

Well, no. Orbx covers ALL Australia, and they currently cover teh Pacific Northwest, The Pacific Fjords (Canadian Pacific Coast and south Alaska near Ketchikan) and Northern Rocky Mountains (ALberta, Montana like Glacier NP). They'll have a Central Rocky Mountains later on and also Northern California. Their plans are to indeed cover all of the US and Canada for FSX.

It is, I love Mega Airports. FlyTampa is good, I have Kai Tak, but they too only do airprots and surrounding scenery.

SO MANY CHOICES!!! WHAT DO I CHOOSE!?!

I'll just wait, but I think Fly Tampa Might be the winner. Although I like Orbx, I don't do GA, and Hardly and Australia and Alaska flying. Maybe I'll try it, but remember, I still don't have FSX since my Computer died.

Might not be what you're after but the UK is pretty well covered in terms of high detail scenery.  I use VFR Generation X Photographic Scenery from Horizon which in three volumes covers the whole of England and Wales.  They also do Scotland now too.  On top of that, UK2000 do a series of airports, covering every single one from the major international ones down to the minor VFR airfields which all blend in seamlessly with the photo scenery.  I've also complimented these with Treescapes, a product from Earth Simulations, which populates the flat photographic landscape with thousands of accurately placed autogen trees, giving it a far more realistic 3D look.  To top it off, I also have Earth Simulations' Alderney and Isles of Scilly scenery, which is (in my opinion) as detailed as OrbX FTX, but covers much smaller areas.

Out of the box in stock FSX, the UK is a bland and unnatural desert landscape. The above products completely transform the experience into something very real and lifelike!
