The graphics are really just ..... wow! I'm actually not that type, the graphic details were overly important. But here convinced me real. Very nice to look at, great detail and on my system with consistently high resolution absolutely smoothly playable.
The gameplay, especially the various fighting mechanisms, I felt in the beginning as a slightly confusing. But over time I came always better cope with it. Ultimately, even with mouse / keyboard combo on PC easily playable, if you take a little time to practice (and not total gross motor Wurstfinger has .... :)).
One point deduction's from me, because I would have liked a little more story and RPG elements. No doubt the massacre with the Orcs and Uruk really fun until the end, but the story itself is (for me at least) a little too short.
