AC Valhalla starts well. Norway is a gorgeous frozen wonderland and the story is given a strong start. Travelling to England it gets even more beautiful. And that's the games best feature, it's beauty. But you soon learn that it's going to be a long slog, and here's why:

The story arcs (or counties) all have the same structure. A few quests and then an assault on a castle or monastery at the end. It gets a little monotonous especially since there are over 15 arcs.

Due to the nature of the game, it struggles to character build. I never felt invested in any of the characters.

For a game that relies so heavily on swinging axe and hammer, the combat is outdated, lacks impact and never feels intuitive. It got a little better as Eivor progressed, but never felt good.

The skill tree is confusing and convoluted. Getting skill points never felt exciting because the upgrades are meaningless.

The game is stretched thin by forcing the player to search for materials for upgrades. Materials which are in a locked chest, behind a locked door, which you need a key for, which is behind another barred door 30 meters down the road. Frustrating.

I did enjoy the ending to the main storyline. It's last few hours were were fun, even if they didn't give a satisfying conclusion.

Verdict:

A decent start and a good ending aren't enough to save this monstrous games bloated mid section.

There are parts I enjoyed, but a lot I didn't. It's nice to look at and if you enjoy spending vast amounts of time exploring sprawling vistas then go for it. But I just feel neither the story or the gameplay are good enough to sustain the enormous length of time it takes to beat.
