The main reason I stopped playing Pillars of Eternity is because I’d need a month-long holiday to make meaningful progress through it, but though I liked it, a host of minor annoyances played their part too. Retro-for-retro’s sake UI, a conscious aversion to brevity which I felt sometimes undermined rather than supported its world-building, overly micro-managey combat, and most of all, janky stealth. I always play a rogue if I can, mostly because I’m a kleptomaniac in RPGs, but in Pillars stealthing one person involved stealthing the whole party, whether or not they were any good at stealth. It looked silly, it got fiddly, it wasn’t very effective in combat and it felt wrong.
Fortunately, stealth is one of several areas of Obsidian’s RPG which is due for an overhaul in the upcoming 2.0 patch, which adds some of the White March expansion pack‘s features to the core game.
