... then the only thing I believe that needs to be said is that even the puzzle itself is WORSE.
Terrible. Shame on them for releasing this game and calling it a sequel. If you must play more Puzzle Quest, play their "unofficial" sequel Galactrix. That one was inferior to the first as well (as can be seen by most reviews), but at least the puzzle part of it was something new.
I would never think of giving a game anything below a 4 unless it truly was a misleading, horrible game. This game is one of those.
I got this game because I had seen the PC one and wanted to play it. Without the book, many symbols didn't make sense. I abandoned the campaign and played the individual ones. I think I would have played it more and liked it more if I had the manual.
