User blog comment:ElessarTheOnly/PRM Weapon Pack considered harmful/@comment-44989155-20200204190405

Regarding all the extra files in the pack itself, I can probably explain why it happened. During the LA DC 1.4005-1.4007 development the team wanted to optimize the effort as much as possible (to finish with LA DC as soon as possible and start working on the New Project) and because most people on the team liked those weapons very much, they mostly concentrated on the branch of the game with all the weapons added. So you can consider the PRM Weapon Pack to be a "definitive" version of LA DC, and uninstalling it makes it kind of a cut-down and less tested version of the game.

PS: I was one of the original co-developers of this pack during the 1.4005 development (I left around the time it got released). So a lot of things might've changed since those days.
