To be fair, a few of the mods are not very descriptive as to what they do. It’s the reason I have not tried some of them them.
I think a lot of people just auto install mods because there is a deal with other games that allow modding that modding always equals improvement. That somehow a modder knows more than the actual devs of whatever game. Which, as far as CDDA is not always true.
For instance, I have heard of Kenan’s Mod. But for the life of me, i have never seen a description of what it does. Unlike, say, Magiclysm which is self explanatory.
From what I understand about PK, back in the day it’s claim to fame was adding items, creatures, and locations from the Doom franchise along with a ramp up in difficulty for the versions around when it was actively maintained (unless it’s been adopted by someone).
Still, would be nice if more of the mod makers actually went over what the mod does as opposed to “this improves things, add this!”
