Outstanding game, but rent it*, don't buy it. Gets a little bit repetitive. Reminds me a bit of Ninja Gaiden (last gen). Biggest 'wow-factor' I've experienced on 360. Has plenty of room to grow, but really has that fresh excitement that a new console feature title should deliver.
Atair better learn to swim by the next version. The short zoom on the map is also a bit annoying.
Also a bit talkative... it would be nice to skip the long-winded saved peasants, especially since you cannot move on until they repeat their repetitive replies.
* - Blockbuster, rent for 7 days ($7-8), 7-day grace period, auto-buys the game on your card, 30 more days to return for 'auto-buy' refund, $1.50 restocking fee. About $8-9 bucks for 5+ weeks. More than enough time for most games, save ncaa football for me.
