No, but I did recently buy the CE of Skyrim and Pandora's Tower, both for the art books and Skyward Sword, because of the special controller. I do plan to get the CE of The Last Story because it's a great game and also for the art book.

Of upcoming games the Bioshock Infinite one looks really cool and perhaps I might get the CE of Epic Mickey 2 but I'm afraid we'll only get the regular version in the Netherlands 🙁

I added the Halo 4 one to my collection recently, but it was really underwhelming...granted, I didn't open most of the extra rubbish. Just felt really half-baked, though that little journal they included is sort of interesting.

If its a great bonus I may pay the xtra cash but normally I just buy the game, besides it was always the preorder exclusives in Japan I was envious of lol.

I don't intentionally Collect Collectors Editions its just that I always get suckered by extra in game content mind you the key chains the statues and the art books and soundtracks can be cool I really end up buying the CE's for the extra in game items or levels and the rest of the stuff gets looked at once then put on a shelf so now I have boxes and boxes of extra stuff now don't get me wrong I am not hating on people that collect but I am not a collector that buys games or collects them for value I collect only for myself and personal enjoyment and I just feel most of the time for me the stuff outside the game ends up being a waste but they always seem to slip that 1 extra content piece in the game so compulsive me just has to buy LOL

It really depends for me. I have to really like the special case, or fancy trinkets included. Like, I had to buy the Skyrim CE for my PS3, there was no question about it for me. I always buy MMORPG CE's due to the in-game items no matter how shitty they are. But for like anything else I just go with the normal edition. I can't name you one game sound track I've listened to that has been packed with a collector's edition.
