Veilguard is a direct sequel but can be played with some light context
Rdr2 is really great and is technically a prequel

Exactly seeing society and environment shape something is so cool

If i had to pick a fav it would have to be norse but I really love cross referencing pantheons ie all myths and religions tending to have a thunder god and seeing how they deified

Its chaos out here

I did see a little friction with Emmerich and taash but even that was nice
