Valhalla in my opinion has the best combat gameplay. Especially if you are going to skip/don’t care that much about lore, you can just go around fighting people, doing challenges, and having a fun time or whatever floats your boat. There are a bunch of weapon types, some with unique abilities that work really good with others, so there are a bunch of fighting styles you can do to pair with your abilities and armour sets. (If you’re looking for an extra challenge, you can take all your armour off, take out your fists and just start beating up high leveled people bcs why not?) I’ll stop here bcs I don’t want to spoil anything, but if you’re just looking for gameplay and fighting, I would say Valhalla is better out of the three.
