I got a lot of enjoyment out of playing this, I was sceptical at first since I read a lot of bad reviews on large gaming sites but it seems those websites were incorrect as I found this to be one of the best games I've played in a very long time.
The bosses require thought and you need to figure out each weakness, button bashers will dislike this game instantly because you can't just spam... you need to think.
The game has a few bugs which I won't go into as there aren't any spoiler tags on play.com
Also you should get an email from play.com with the General Kota costume around 2-3 days after purchase.
Great storyline, great graphics, good combat system and requires thought... it was exactly what I was looking for in a Star Wars next gen game.
