I’d say FO4, despite anyone’s thoughts on that game otherwise, really pulled this off too. Same with Divinity 2.
That is opposing factions battling eachother in the gameworld. It really makes the world feel more real and alive. For example in FO4 you could arrive at a super mutant base being attacked by the Brotherhood of Steel, and suddenly a group of raiders joins the fight for a massive free for all. Regardless of people’s opinion on that game in other areas, it gave the game soul imo.
Many games have the problem of feeling empty, soulless and entirely player focused when it comes to immersion, atmosphere and gameplay. Having been a gamer for 20+ years now (yes I’m old), I’ve experienced my share.
In Divinity 2 there was much of this same thing. Different factions battling eachother not just behind the scenes but ingame. The various factions being at odds and such brings out this same feeling of the world being lived in.
So with someone with an almost autistic eye to details these things caught my attention early in GD. In areas you can see beasts fighting aetherials, aetherials fighting bloodsworn, and humans fighting humans. There is also a masterful placement of such cases where it makes sense. Like in the troll cave to deadman’s gulch the battle between them takes place in the end and beginning of these areas.
Instead of enemies just standing around in the world “waiting for the player”. This helps with immersion by making it feel like the player is there with the world, and that the world isn’t there just for the player so to speak.
On a lore and worldbuilding level I also like the fact that 2 dominating factions have the world as their battleground, with humans being caught in the middle as a minority just trying to survive. That’s another topic but just wanted to throw that in here too.
Anyway! I just wanted to give praise to how this is in GD. Because for someone who cares a lot about the “feel” of the world, this does have a big impact on the enjoyment of the game. At least for me personally.
