I, and some friends, play Albion Online. It is free now. It is not much, but with friends is more fun.

Wurm Unlimited/Online has some good in-depth crafting. Crusader Kings II gives you a bit of a taste of the Dance of Dynasties.

WoW Classic start at 27th, it should provide some nostalgia gaming if nothing more.

I am a long time Guild Wars player. After a couple of years away from the game, it has gotten away from me. But it is still a great game.

depends: Witcher 3 if you want to adventure, Rougelikes if you want permadeath, crusader kings 2 if you want the dance of dynasties, mordhau or something like that if you want on the battlefield. but all of it in one game, there is only CoE.

any other suggestions? :x

Project Gorgon is keeping me busy. It's in beta and still has a few rough edges here and there but is regularly updated, regular events too....very good fun,

Fight, craft, loads of different fighting styles and lots of skillsets, explore, quests etc. From memory you can try it for free & play on the tiny starter island so as to try the game out before setting out for the big game world. Steam or via their own website IIRC.

Pillars of Eternity II have a lot of replayability potential, and on extreme complexity can be challenging, immersive and long enough. I like simple but very rich class system in PoE2
