You know what guys I have a bunch of Asian releases and what I notice is I buy them on release at its lowest price and soon after they sky rocket in value then it settles in and drops some in value but like i said it drops some but not to the value of what I purchased it it still maintains a higher value then when I got it on release.
If you notice not many UK, German, Canadian and US releases gain a lot of value. Of course their are a few exceptions for titles each country releases but for the most part Asian titles gain value after you purchase them due to more limited print runs and wether people want to admit it or not a slip with characters many of us can't decipher, it does add a unique look to the overall presentation of a steelbook release.
Take for example, FNAC; they have their sticker and extras either booklet or poster or something else, JB HiFi has their sticker and add a booklet and Asian titles add a slip or slipcase or art cards or booklet or all of these items and these things make them more sought after. We all know we go nuts for stickers, booklets, posters, artcards, and other items and that's why they are highly coveted and we want them in our collection by us and me myself. Me I love Asian releases and their awesome undecipherable characters it just adds a nice touch and diversity to my collection.
This is just my opinion guys so don't be rough on me. I respect the opinion of members not liking or not being as fixated as I with slips. I will hunt hard as usual for all releases that catch my eyes wether they are Asian releases or releases from anywhere else in the world.
