Lar... if there ever was a multilayer game or mmorpg released. Please keep the story and locations totally separate. As much as I'd love to have an online experience from Larian, I wouldn't want the story ruined from mmorpgs. The story of an MMORPG is never completed.
I just don't want 2 see divinity ruined by idiots that think its good 2 skip sceens & rush through the game which will happen if it go's multiplayer.
Runescape prevents this. Most additional lands, higher up weapons, teleport spells, armor and access to different lands require certain quests to be done. It is possible to rush, but their play realm is extremely limited. And example is that you need to kill a dragon after figuring out clues on how to find it to wear rune plate body. You need about 75% of the quests done to get full access to the realm.
I'd hope Larian would follow this idea.
