I found the game to be meh when it first came out but the ending of it had me buying Shadow of War when it released! The nemsis system is interesting it's just a shame that it got TM.
I also like the mixture between AC, and the batman arkham games, for the combat!
Yes, the nemesis system is interesting to me too. I think the combat system is not bad. It would be better if I didn't get one shot from every archer boss I see :P
