We consider packaging to be quite effective when you can tell at a glance just what awaits you inside of it. Take this God of War Entertainment Pack, for example. There's the "Deep Red" PSP, the Superbad UMD, the critically praised God of War: Chains of Olympus and ... well, there's also a PSN voucher for Syphon Filter: Combat Ops, which isn't pictured. To be fair, that's simply due to the lack of excitement incurred by a piece of paper with some obscure code on it.
Also not pictured is the price tag of $199.99 [£100] and, perhaps most importantly, a disappointing label which reads, "Not for sale until June."
