Video demonstration (German with english AI dub provided by youtube)

This mod makes it actually possible to get the "special quests" for each rival NPC in what I consider an ordinary playtime - apparently you need to play for like 40 hours to get these quests? Shouldn't be random whether you get them or not

These quests are necessary for 100% completion. Both the in-game accolades and things like Steam Achievements.

I haven't tried this yet myself but it must work since it's still on mod marketplace.

Happy gaming.
