From me, I've only been playing for about 40 min and still havnt gottten that much from the game. So far it hasnt gotten repititious and its quite fun. The controls need some time to get used too. If you read reviews from IGN, they bombed AC. I was at the game store today and someone was very upset at IGN and said if IGN isnt reviewing something with master chief or Halo in it... its gonna get a low score. I think IGN has their reasons to rank it like that but YOU need to try it and see for yourself if you enjoy it or not. I cant rate it only from 45 min of gameplay but the thing I didnt really like was in the first 5 min of gameplay I know the "Sci-fi" Twist. I think its a GREAT concept and I cant wait to see how it progress;s in the game. Take care.
