Yep, I've only started collecting CE's seriously recently but I've been collecting steelbooks for about a year and a half.
In the beginning, I paid far too much for practically every futureshop steelbook I bought. Nowadays I'm a lot more cautious about my purchases and I do believe I have developed a certain sense for what steelbooks are worth etc.
CE's however are still a little confusing to me. For instance, I'm pretty sure I read at least 2 separate articles detailing how "limited" and "hard to get" Halo 4's limited edition was going to be but they made over 450,000 copies
I now think that retailers/publishers purposely lie to us so that we preorder something thinking it will be rare when it most certainly won't be.
Btw I knew the articles on Halo 4 were crap, I swear there were still halo 3 legendary editions in my best buy up until like 6 months ago
