Hello Kaplan,
As you say the emulation of P3D/FSX aircraft in FS202 will probably be poor. On the other hand, the offer of aircraft in FS2020 is very limited and is in majority only light GA's.
So I am thinking of keeping two sims, one for the scenery, e.g. flying along coastlines and in mountains, valleys etc and one for still experiencing the goodies and specialisms of our beloved aircraft as WW2 bombers (Lancasters, B-17's, B-25's etc), transporters (C-47's ), fighters (Spitfires, P-51's, ME109's) and piston engined airliners (L049, DC6 etc), the investment beeing done.
reg.,
