Red Dead Redemption 2 just got a new mod titled "enRAGE" that adds a fully functional nemesis system into the game. This makes every single NPC have a name, traits, quirks, a trade, a faith, a family and a life story. So people you meet turn up again in the same towns with the same face and the same grudges as it adds a full memory system. The map is now populated with 8 factions that are constantly at war with each other, having their own hierarchy and captains that you or their enemies can take out. Every single encounter is remembered, including exactly where you wounded them in the case that they survive the fight. This means that RDR2 now has a fully functional faction war that goes on all the time with this mod and factions will remember your actions against them. There is a ton of new dialogue and you can even interrogate NPCs now to get additional information on their friends and allies. This is an extremely impressive mod and it's now available in early access to download for anyone who has RDR2 on PC.
