Summary, if anyone cares:

-level design with larger levels and more interconnected world design
-deeper lore
-fashion is back
-co-op and PvP is back
-has "old school inspirations"
-high fantasy
-Set in[early medieval] Britain or Scotland
-dark, deep ocean creatures like sirens
-more creativity in builds (not sure I interpreted it right?)
-more immersive, more room to play how players want

The game takes a lot from Gaelic, Celtic, and general British Isles. Some really creepy stuff in this game, dark fantasy through the roof.
