The little info of wots4 sounds good. It seems like age factors into creating a character now or something like that. It is set around a harbor with conflict between shogunate, foreigners, and anti-foreigners. If I'm understanding it correctly, after certain events, they now show you a flow chart that helps guide you on a different path in the next run. It sounds like it's because they're adding more choices for those events and it is to help the player out.
there are scans but the quality is really poor
