How to play Even Deeper Regrets: The Official Guide

About Even Deeper Regrets, from BoardGameGeek:

Gameplay in Even Deeper Regrets is the same as in the base game with one major exception: you can now choose to start each day Inland in addition to Sea and Port! Inland, you can fish from three River shoals or one Loch shoal, both of which have a higher risk/reward ratio than the Sea. 74 new fish and 25 dinks await inland! You can also fish an entirely new sea of fish, with 117 brand-spanking new fish to discover. Mix them together with the base game fish or play with just the expansion fish, it's up to you! New polyps introduce a new mechanic: every polyp is worth more for each other polyp in play. New items and equipment are available including a new supply type: pets! Pets sit faithfully by your side and offer a persistent benefit - but they can still be lost at sea, so try not to get attached. -description from the designer
