I don't know about anyone else, but I think there needs to be a Timeline page for everything that's happened in the series from 0 up to now, as well as before that.
Yakuza 4 + 5 on PS Now???Edit
I think it should be added to the news section of the front page since it may be a moderate deal to some people. Also, I agree that there should be a timeline page for everything that's happened.
