Its a huge and very nice looking artbook. A bit pricey but worth every penny to me. Lon'qu was my favorite character in this game and Tharja rocks! They released a nice statue of her that I may have to pick up sometime :P.
I hear something about a FE and Shin Megami game in the works which gets me extremely excited! As for the DLC I would have to check and see what I currently have for the names and all. I know the game you are talking about. She was one of my favorites! It is pretty cool to play along side her but she doesn't level or really speak which is a bummer but there is a story element to that so I won't spoil it.
Have you ever seen THIS I picked one up a few months ago and it is incredible!!
Need to finish off Madhatter's as all I have left in his is 'Secret of Monkey Island'. I want to do Sacred 2 for Gackt's club and then possibly polish off the Mass Effect series, in which then I will do Enslaved and Beyond good and Evil for Raj's club.
2 bosses in particular were hard for me which were Smough and Ornstein and Lord Gwyn. On higher playthroughs the 4 Kings became very rough.
It will at least pose a challenge. A lot of people are put off by the learning curve at the beginning, so a lot of people that gripe about the difficulty haven't actually fought the bosses that are hard.
