For CE Guides, I recommend look for RPG-based guides, or even those with a lot of statistical / historical information (eg Assassin's Creed series). This are always sought after and can fetch good prices on Ebay (if you are looking to speculatelah). There are also some Action games like Bayonetta & Batman AC, and you can tell if they got high production values by the number of pages (anything above 300 should normally be good buy).
Personally, my favorites are :
1. Bayonetta (superb production value, great art, classy design)
2. FF XIII (loads of info, great visuals)
3. Deus Ex
4. Dark Souls (not in picture)
5. Batman Arkham City (2 different covers - mine's Catwoman, comes with 6 lithographs)
6. Borderlands GOTY Hardcover guide (again superb production values)

Probably the only books I regret buying from the get go (meaning should have wait a bit for price drop) was Dead Rising 2 & Star Wars FU 2 because they were less than 200 pages. Having said that as I mention, if the pages exceed 300, you can bet that there's good stuff in there and people will be looking for it. I also have Portal 2 (not shown) which looks great inside though I haven't read it yet.
On its way are Battlefield 3, COD MW 3, Red Dead Redemption GOTY Guide (Hardcover), Assassin's Creed Revelations and UC 3 which I will pick up at Kinokuniya KL (which by the way is having 20% off on game guides - they still have Dark Souls so try to get it coz they sold of their 1st round of stock and I can safely assume it will be gone soon).
Sigh ... missed out Skyrim - 676 pages of CE goodness with DLC. Ebay selling at USD 70 and looks like it will be the first CE I will pay close to 300 for.
When added to the CE I just got - thought I share this coz was checking my dragon's condition, Skyrim stuff alone will be close to RM 1 K! Worth every penny though
