Each of the mods are there own X project

PEx is the original PE converted to use the new game engine. A few graphical examples are provided, but it is basicly the original scenarios and unit models., The cockpits, trees and buildings have been updated to work with the new object attributes. This will always have the most recent release version of the game engine..
http://pedg.yuku.com/topic/2109/PP2-x PP2x is an upgrade for the MultiPlayer mod PP2. The download link is in the first post of the thread.. It uses the same buildings, trees and landscape textures as PEx. The only thing missing for compatability is the calibration of the guns not included in the original PE.
http://pedg.yuku.com/topic/1719/Panzer-Elite-three-mod-LINK-containing-Ostpak-MvR--BritPak PE3 is an attempt to combine PEx, Ostpak, MvR and BritPak . The download links are in the first post of the thread. The main problem is that it uses landscape and object attributes that were an attempt to address missing physics in the original game engine. The result makes the new AI think every stream is a lake, while every tree is a bocage.

Point taken that the compatable mods thread of PEDG is confusing. Please note most of those mods used beta version 16.4 and are now 5 years old. 16.10 was the version of the "you can't stop me", so 16.4 is realy old. ;) 16.11 was the first version with a PE3 check.
The dll and exe files from PEx Release 1.03 can be added to any X mod. The improvments may not be obvious. Most improvements allow new posabilities. The screens you see from some beta testers were made after they combined PEx beta files into PE3.

I am not suggesting any mod, only trying to give the currrent development for each. I only have dev mods of PEx, PP2x and Brit44x installed.
