I want to buy a hand-made collection of Saints, but there are too many kinds. What's the difference between mainland licensed, Japanese version, Hong Kong version and so on?

Actually, it doesn't make any difference. Everything in it is the same, including the first edition and the replica edition. The so-called continental edition, Japanese edition and Hong Kong edition are just posted on the box, and there is no difference. I also bought them one by one. But remember one thing, you must buy brand-new ones, not second-hand, because most of the second-hand ones are from Japan, and you must never ask a Japanese to play with the rest! Because some of them are no longer published, they are relatively expensive, such as Libra, Lion, Fairy Girl, etc. I bought the cheapest one, about 245 yuan, and the most expensive one is about 6 yuan. I hope it will help you!
