Well, unlike previous KQ games which I almost uniformly loved, KQ7 was a bit of a mixed bag for me. There were some things I liked a lot about it -- the art (yes, I'm one of the few who like it) the alternate endings, and the characters. There were also some things about it I really hated -- the puzzle design was annoying, particularly the many 'timed entrance' puzzles with the dog and bogeyman, and in my opinion the second half of the game was rather lack-luster and repetitive. In general I think it's rated properly -- fun but not fantastic. Put it this way: I've played all other KQ games at least 3 times, KQ7 I only felt the need to play through once, plus the alternate ending.
These are my principles. If you don't like them, I have others.
