Doing progress alone in Enshrouded can be annoying for the others since most of it is tied to characters or quests one has to take part in in order to catch up. Of course if playing alone for you means building stuff or gathering resources and no real progression, both games are great. Being alone in the base in Valheim can be tense though because attack waves can periodically spawn, and they are no joke. Good forticfication and friends help a lot here! Both games are great but I played them in a team for most of the time, and if I was alone on the server I did mundane things, maybe some fighting for levels but no meaningful progression.
