I share your pain! lol.. honestly i do. sometimes I feel there is so many items, vehicles, factories, missing in certian paks.
Gotta remember tho.. some pakset are created by one guy, others created with multiple persons with their addons.
Pak128britian idea was born by one guy, and the idea took hold, so many people can create addons to be included. Pak96comic, well its new, but not sure of its popularity.
If you wish to see pak96.comic grow with fantastic vehicles and such, perhaps you could look at creating some?
Have a look around in forums for how to create an addon. Feel free to ask questions, tips, and suggestions on creating an add-on. We are here to help.
(Btw, im waaaaay to busy to create some addons for pak96.comic, sorry! lol)
