No doubt.
I had to butcher my party rogue at one point and replace him because he got glitched into a wall and I couldn't find a way to get him out or leave the area, or even kick him out of the party. If it were my main character that probably would have been the end there.
No, the party wasn't rested. They walked to the fight straight from the compass.
When you get back, the game is like, "oh no, people are dying, we have to get in their and help." It wouldn't feel like much of an RPG if I went and had a pint at the bar before the adventure.
All that wouldn't be so bad if the game didn't hide monster statistics and disallow retreat from the map during a fight and disallow retreat when half a dozen monsters are standing on the body of a down but not out comrade. Even all that wouldn't be so bad if on top of it all the game didn't throw curve balls at you. That's my grip - that the game isn't set up for hardcore. Take a game that is for example, Path of Exile. When you are leveling your character up in that game and provided you are pursuing a standard and obvious design, you can FEEL your way through the game. If you are losing too much life, you can advance health. If you need damage, then damage. If the monsters start becoming too hard, you can check your gear, go back to a previous area, party up, and so on and on. It was designed with the hardcore experience in mind.
Other than beating the game in regular mode and memorizing everything because it doesn't even change, what can you do in Pillars? The game goes out of its way to be dense.
It's not so much a "have a pint" thing as a "Oh, no, we're not rested and we're gon' get killed if we don't rest up and think this through carefully before committing".
Granted, I think that the dialogue in the game should allow you to really act that out way, way, way more often, but that's pretty much it. In Hardcore, you really need to stop and think before you do anything at all, considering your options. It wouldn't be hardcore, otherwise. That said, I specifically do not run hardcore myself because I don't trust games to not arbitrarily and suddenly screw me over due to bugs or crashes or just plain weird mechanics suddenly acting in a completely unintuitive manner. So, yeah.
