I just did that side quest yesterday. Female Eivor's delivery on these lines is much better than video related.Just watched a quest where a "raid-loving" woman tells you to set her house on fire so that she can get wet enough to fuck her husband.
It's pretty much a sidegrade from The Witcher 3 with significantly better open world exploration so I would recommend it. It also seems to have better build variety than Witcher 3 but that's not saying much. I'm about fifteen hours in doing a bunch of exploration and side quests but I still don't think I've hit the main story unless the main story are just all the kingdom arcs with an epilogue dealing with the templar faction.I mostly care about narrative and world atmosphere\immersion. Last open world games I've played and liked was Arkham series and The Witcher 3.
Should I try Valhalla?
If you're waiting to see whether or not the campaign is worth it, I'd keep waiting because the game is massive.
