I played console. I started on pc due to game pass and realised a lot has changed just wanted to know how much the game Changed
As someone who came from console(perhaps close to 800+ hours on console) and have been on PC for around 2 years(about 2000 hours) you should consider this more like a sequel game vs some minor updates as there are SIGNIFIGANT changes from what you know, far to many to list. I said that when I first hit PC back in Alpha 18 and that has only been further reinforced by changes in A19 and especially A20.
I will hit a few highlights though:
Wellness: gone
Learn by Doing: Gone
Skills based on generic ability scores: new(similar to a number of tabletop and even some computer role playing games)
Quests from traders: new
Item durability: completely changed but sort of similar while being different
Farming: quite a lot different, no more hoe or fertilizer or planting on the dirt, you now craft farm plots to plant plants into
many "Dungeon" style POIs: in general, most POI's now have an expected way the developers expect you to follow, a "path" if you will. This path sometimes goes out windows, across awnings and back into another window. Look out for lights that tend to point you in the direction they expect you to go(flashlights or lanterns, etc)
im sure to miss other major stuff.
