Too many reused assets.
Landscape difficulty is way too low
Feels way too segmented and disconnected. Where Moria's various zones had many open and seemless juncture points, each of these zones has one narrow passage to the next.
Doesn't really feel we're in very big spaces. Gundabad you would think would rival Moria in space, but we are being tricked by elevations and each zone has large masses of unplayable areas.
Storyline is not great. Instead of a war, seem to be in a sparsely populated post war landscape with very little in the way of resistance.
Picking rocks sucks.
Pros would be the connec to Angmar is cool and I guess that we got to see Gundabad at all. Overall though, giant Meh.
Phrasing! Doesn't anybody do phrasing anymore?
