I might have been interested in trading, but I can't not notice that you posted this request 10 hours after the Dystopian Humble Bundle expired, which contained Rain World. A bundle that lasted 14 days... talk about bad timing. Maybe some other time.

[HAVE]:
-Steam wallet code of $30.00 USD

[WANT]:
-Man O' War: Corsair - Warhammer Naval Battles (GOG)

DONE: Traded with DebbieL.
