Yakuza 0

• From what I've seen, you can't miss anything (maybe you can if you finish the game, not sure, but between chapters this isn't the case)
• In the top-left of the map is a pretty damn big minigame for Kiryu, so don't miss that like I did
• Enemies give trash money compared to your businesses, especially as you get them stronger. And since money literally equals power in this game, you can 'grind' (but not really) your abilities into the sky once you unlock the businesses for each character
• Each style has different heat moves that count towards the CP bonuses
• To get strong enough to have a master teach you new moves, you need to have unlocked an ability space next to one of the locked 'M' spaces.
• A lot of times, if there's a business you can buy or advertise within with someone that has a friendship bar in it, you need to max out that friendship bar before you can add it to your business.
• To get new arcade games, max out the friendship meter of the arcade lady within the SEGA arcades, one in each city.
• With Kiryu, many of the people that you encounter in substories can be hired as a manager later by talking to them outside of your office (usually, there are other places you can find them sometimes)
• Either Kiryu thinks someone wants to fuck him, or they want to fuck him. Sometimes they fuck him anyway.
• The phone sex parlor has three women you can sex with for completion points, and a couple more substories that just have you watch a cutscene where, essentially, Kiryu is taken against his will.
• If you see a Mr Shakedown, save before taking them onif there's a phonebooth nearby. Chances are good they'll clean you out, so being able to load is a godsend.
