Dragon Quest XI: Echoes of an Elusive Age

• DLC/Preorder stuff is unlocked in the Misc. Menu.

• The game autosaves when you zone.

• You can eventually reset your skill points at church. Not only should you play around with different specs, some nodes will unlock bonus skill points.

• Some harvesting points appear only at night. Check your map to see the locations.

• Quests that require peps to complete can be tricky. You can always help trigger peps by beating on your allies with crappy weapons.

• On the final turn of a pep, you will see the aura on the character's portrait begin to fade.

• You might see little bullseye targets around the map. You eventually get a tool later to take these down.

• There's some battles where you are meant to lose. The earliest one is
  a sudden ambush on a stage taking away your party members except Erik.

• Right after the above battle you are a meant to lose, it's safe to ignore the game telling you to beeline to the next objective and explore.

• The first time you enter the Casino aim to get the 500pt recipe book. Abuse the auto-save feature and move on. Don't bother with the other prizes until the high-stake tables/machines unlock.
