Pretty much as above -
 
 
some examples
SF2NA
The campaign structure is different to all the other games - so if you fly an A-7 and the AI F-14s dont take out the bombers and the landing fleet get taken out then that can end as stalemate
 
In SF2V  
Even though there is a DMZ there are no ground forces - so with no ground war  you essentially fly a series of missions within the time period. In the campaign you will get proper unit representation and the different skins - but your objective is to survive the tour really (pretty much as the real thing).
 
In any of the 3 campaigns historically the best you can hope for was a draw - i.e. LBII achieved clear objectives for the US - but North Vietnam still went on to invade South Vietnam and win.
 
SF2/E/I
This is more straight forward - you get a FLOT and ground forces actively engaging each other - With these you win by making sure your ground forces get to the objectives 

If you add a patch then the aircraft list will reset to default - but should still include the add on aircraft still
 
So this happens for ever exe and every mod install?
 
 
Try open a mod folder and cut and past out options.ini and version.ini
 
run the exe for that mod - the game will recreate those files -  and see if you can get the add on jets back.
