-Pretty much no mistakes in regards to historical accuracy in terms of mythology, runes, and such.
-Good variety of class options (including ranged)
-Good difficulty and balancing
-Exposure feature which breaks up slightly monotonous feeling of doing raids (missions)
-Story doesn't appear too interesting after first raid.
-Your clan village actually feels very empty. Apart from NPCs, there is only 1 random guard near the runemaster. The clan hall is empty, and YOU CAN'T EVEN SIT ON YOUR THRONE!
-Sometimes the dodge feature is a bit useless, because some Mini bosses/Bosses timing when the attack actually lands are unclear (Eg: The Jotuns kick damages you like a split second or so before the leg is fully extended, and it's not so easy to read when its coming) and it's close to impossible to dodge unless you read what attack is coming.

Overall: 8/10, but that's because I appreciate the effort put into the setting and accuracy of the game, rather than small issues with gameplay. If the price deters you for what it offers, just wait for a sale.
