-When talking with someone, always exhaust all options unless stated otherwise.
-When a disc icon is showing up, always save first! (save often anyway, you can die in various ways).
-Instead of the straightforward go back the ways you came from, i immediately mention the next part of the map you need to go, making the walkthrough a bit shorter.
-Because of all the many achievements, i had to shuffle parts around, if you spot a mistake, please let me know!
