Who plays with Solution (I curious way once the second pass attempts) gets only reveal what he really needs at this time, otherwise referenced to other chapters with a higher "spoiler-degree". The "Secrets" chapter are again packed with all kinds of information off the game and the storyline.
Who is a big fan of artwork and in-game images, is well advised with the CE thoroughly. Who needs to look something up short, for the ranges also the normal version really just a game guide.
Conclusion: Accustomed well manufactured piggyback product and indeed worthwhile for collectors with the CE. Any other use on the (lower) normal version of this Game Guides.
Yours sincerely.
