I’m curious how long it would take a NEW player to beat the core game? If they had access to the wiki and when needed YouTube but didn’t have someone standing next to them telling them what to do. In other words they try the jumping puzzle or what ever they were trying to do a few times and if they failed, then go look it up. How long do you think it would take in hours?
And I mean the main story and all achievements for pve.
Ignoring the all achievements part, story and world exploration could be finished in a week or in like 6 months. Honestly my suggestion would be to not rush it as it defeats the purpose
