I decided to order a PS4 after all, and I bought Yakuza 0 and Yakuza Kiwami to go with it. I may get more Yakuza games if they release the ports of Yakuza 3, 4, and 5 here in the U.S.
I may even get Sleeping Dogs: Definitive Edition one day because I'm really digging these Asian gangster-themed action games lately.
