I may have played all the Ryu Ga Gotoku mainline games, but RGG0 is still one of my favorites (aside with Kiwami 2). I have 600hr+ on Steam and I really wanted the DRM free version, so I have my very own copy of the game. What I like the most in this game is the strategies to get the most money as fast as possible! It's really interesting how my 1st playthrough differs from my last in this way. This said, everything is gold in this game : great story, all-star cast, so many different kind of substories and mahjong !!! I definitely will play again the other RGG games on GOG (and I wish for Gaiden also!! Pretty please)
