Quick Start: a new game now lets you choose Quick Start (the opening told in short) or Full Story (every scene of the original opening).
Guild management: send your groups on quests from the Quest Board, earn reputation, and level up your groups.
Guild ranks: after the main story, raise your guild from Bronze to Silver, Gold and Legendary. Unlock elite contracts, bigger rewards, and a Legendary Guild Feast with the girls.
Guild upgrades: improve the Kitchen and the Vault.
Quest Log: a new Quests button always tells you what to do next and where to go.
Scene Gallery: rewatch every adult scene you've unlocked from the main menu.
God blessings restored: choose Odin, Thor or Freya again, each with its own perk and achievement.
Morgan's hidden story scenes can now be played.
Fixes and improvements

Achievements no longer unlock all at once.
Combat is rebalanced. Potions, leveling up and health bars all work properly, and dying lets you retry instead of sending you to the main menu.
Skip no longer skips the animated scenes.
Long forced pauses can now be clicked through.
Many story continuity fixes: characters introduce themselves, time-of-day lines match, and events happen in the right order.
Fixed Susan's and Mira's affection bugs, along with dead ends, map spots that went nowhere, and quest hints that asked for the wrong items.
Building the guild now tells you where to buy materials and what the whole build costs.
The interface has been restyled to match the game.
Russian, Chinese and Italian translations heavily corrected, including a bug that showed wrong letters all through the Russian text.
Game size reduced by about 500 MB.
Existing saves still work.

Thanks to everyone who stuck with the game.

The "Achievements no longer unlock all at once" line is true for new players on this build, but anyone who already got the mass unlock keeps those achievements.
