This guy actually does a great job of covering most of the bases. Not all, but c'mon - he's only got four minutes.
[update] Oh, and the same dude put together a 35-minute playthrough from the start of the game! It shows the tutorial fight and everything - and, thankfully, he's only speaking for like ninety seconds of the whole vid. Awesome.
I could seriously just chill out and watch this game all day. Cannot wait for the 3rd.
