I'm sorry this review arrives late, but The Bard's Tale 4: Barrows Deep is stubborn. Trying to power through it is like trying to solve a great pile of crosswords in one sitting: your brain would turn to mush. You could cheat - The Bard's Tale 4 includes a walkthrough out of the box - but you would rob yourself of the point of the puzzle in the first place. The answer doesn't really matter; it's the process you undergo to get it and the satisfaction you feel when you do that counts. In this way The Bard's Tale 4, one giant collection of puzzles, can be enormously satisfying, but force the issue and you will bang heads with it. It cannot and should not be rushed.
The other important thing to know or remember about The Bard's Tale 4 is where it comes from. This has its roots in crowdfunding, and is not a big budget game with a huge team. Character models are dated and cutscenes are slideshows with filters on, and a variety of bugs (a huge second patch for the game has just been released) forced me to reload upwards of 15 times. This is particularly annoying in The Bard's Tale 4, because saves happen at little pillars and not freely from a menu, meaning you have to redo progress each load.
But what other games do you know that come with a printable Code Wheel for solving puzzles? What other games do you know with a bard hero class powered by booze? What other games do you know with a live-action, evolving story recap when you select 'Continue'? What the Bard's Tale 4 sacrifices in polish it makes up for with personality.
