One thing i think would add a very nice and personailsed experience, also easy to make is a sound revamp for the game. I mean selectable different types of moans, little phrases, etc.
What's you opinion about it Gizmo? We have the same sounds since 2012, so more than 10 years now. I see a lot of potential in this neglected part of the game, also a lot of potential to involve players into making sounds/voice packs.
I'm not a dev nor a programmer, but i could easily make a little addon to change the moans in the game back some years ago, and i can tell it provided a whole new level of experience. Sadly do to my programming knowledge and complicated multiplayer options, i abandoned that project, thinking it will come to the game also sooner or later.
