Yakuza 3

- Unlock guard breakers being added to the end of your combos ASAP.

- Carry food with you always everywhere. Real fighting involves chowing down dozens of sushi dinners while the boss is doing his trademark bullshit.

- Your daughters happiness is irrelevant and gives you nothing expect knowing she loves you more or something.

- NG+ turns of random battles and lets you finish any sidequests you might have missed. I can't recommend that enough.
