I too played through with Autumn Aurora last summer and I loved it. On Twitter, it appears many Stalker fans swear by Anomaly these days, but I haven't tried it yet. I don't think you'll find a compelling consensus on what the "best" mod or set of mods is -- just people fighting with each other about what they swear is best.
So I guess I'm sorta seconding Neb.
In general, the Stalker mod world is a rabbit hole you could disappear into for months, so be careful.
To make things more complicated, I think I may have slightly modded my Autumn Aurora install, but I don't remember for sure or exactly how. At some point I grew exasperated with all the possible permutations and decided to ignore further modding and just play.
That worked.![]()
