F*** this is a harem book. FYI Miller, lamp shading the harem (if you did it right) wouldn't have helped much, but the CONSTANT references to it is almost worse than the harem it's self.
The biggest problem with this book is that the series here seems to have really lost the plot. I realized about half way through this overly long book, that I don't have any idea what the point of any of this is. He isn't building up to anything, the last big revelation of the series happened at the end of the last book, and there isn't any big bad they are going to have to deal with. It's just some character bamfing around in space.
Anyways, as usual, there are some good ideas sprinkled through this book. Leaving the game entirely and starting up a kind of Star Trek type exploration could have worked, it was even somewhat interesting at first. If it had a plot line and an editor chopped about half the story away, it could have been good.
Initially I thought the strongest part of this series was Millers world building and systems, but that's quickly becoming more of a detriment. It's all just becoming so messy. There are no hard rules of what is and isn't possible. If the main character wants something, he gets it. If the author wants something, he just has them do it. There's no sense of progression or scale or limits. It's just a giant mush of the authors ideas and ESPECIALLY fantasy's.
