While the game is good, I don't think it lives up to the original Pillars of Eternity. I hope future patches and DLCs will deal with some of these points.
Even after the first major patch, there are still some bugs:
1) Movement stuttering when in Fast Mode. It seems like the characters don't know exactly which way to go.
2) Manual save files will periodically delete themselves from the saved game list.
3) When going to ship view, some companions won't appear on the upper deck unless you go to the lower deck then return to the upper deck.
4) When returning to the world view from ship view, the party order will sometimes randomly change.
My biggest game play issues are:
1) Companion quests are uninteresting. In the first PoE, companion quests developed them as characters and furthered the story in some way. Nuanced choices effected the epilogue. In PoE II, the quests just feel like pointless errands with no real purpose and lackluster conclusions. You either pick the obvious, decent choice or be a complete jerk to your companion.
2) The romance with a companion seems like something developers tacked on reluctantly because it was promised in the crowd funding campaign. It requires zero effort on the player's part to achieve, has almost no effect on the companion's interaction with the player, and does absolutely nothing in the story.
3) Ship battles need major tweaking. Any damage you do in story mode offers no benefit if you ultimately end up boarding the enemy ship to complete the encounter. It just wastes resources. The inability to capture enemy ships after boarding them is extremely disappointing. The only way to get a better ship is to sink a ton of money into buying one. There's only one ship you can capture near the end of the game and it can't be upgraded. If it wasn't useful to get the cash from the bounties and loot I wouldn't even bother with this part of the game.
4) Island discoveries were a let-down. Aside from naming them and getting a "good job" and money from Sanza, they don't give you anything. It would be nice if you could possibly help get settlers to them once they've been cleared, or getting a resource boost for your ship, or anything besides just forgetting them.
