Sure it has a few glitches, all games do, but this game is practically amazing and sure to keep you hooked.
It feels really realistic also. When climbing, if it doesn't look like something you can grab onto, you most likely cant, but most buildings have stones, windows, cracks and so on to get you up to where you want to go. Getting on top of some of the highest structures can give you an amazing view of the huge cities you play in.
Having an interactive cinematic also helps make this game fun, being able to walk around or change the view actually helps you pay more attention to.
The best part for me would be the assassinations and the fights you can get into. It always feels amazing to see you run up and kill your target with that hidden blade and then have to run from practically every guard in the city.
This game is an instant classic in my eyes and its sure to amaze you.
Don't believe the people giving this game low ratings because of the glitches.
