I turned on my laptop tonight to write a review of Homecoming, since I beat the game this weekend with my friend djhalcyon. I skimmed my friends page first only to find he'd already written one. I highly recommend giving his a read through since it's more than accurate imho.
The one thing I would stress more is that Akira Yamaoka did an amazing job with the soundtrack. I get chills just thinking about the in-game music (not so with the songs feat. Mary Elizabeth...). Listen to "Demons in Shepherd's Glen" if you can find it zomg.
