I love this setting for 5th ed D&D! I am a big fan of everything Viking and this hits the spot. The various versions of the character classes are well done and thematic and the new class features give a nice change from the usual classes from the PHB. There is a completley new class introduced as well, the Runemaster, that uses a cool mix of wizard, druid and cleric spells along with its own special rune circle magic.
The setting is well detailed and the DM Screen and 24 sided rune die help imerse the players as does the art book (which is very nice!). I have been both a player and a DM now for the game and have enjoyed being on both side of the screen. My player group came into it completely novices knowing nothing of the setting and got sucked into it quite quickly! They were all set for more even before we finished the first session!
The setting is easily accessable and the rules are clear and easy to impliment as well. I highly recommend picking this up and giving it a go! If you have a love of all things Viking then grab this and hit the shore with your raiding party! SKOL!
