RE: Simulators
No problem.
I see 422 complete planes listed, 1483 variants, and 1568 color schemes for G3.5... Also 85 Photofield airports and 266 3D airports.
Remember that some of the variants, airports and colorschemes depend upon having the add-ons.
However most of the "complete planes" or EA's work without needing anything else.
Usually requirements are listed.
Most of the EA's are excellent, though there are many user created variants that are rubbish... same with the 3D airports and Photofields.
