"A bit." It's nigh unplayable. A ton of skills are still broken, sound issues about, they just fixed the camera zoom issue, the combat is horrible at this stage (way too fast, obscured action, companion AI not functioning in areas), the enemy pathfinding is completely non-functional.
I mean, I have never wanted a game to be good more than Pillars. I don't even need it to be BG2 good to be impressed. But I do need it to be a functional, fully fleshed out RPG. I still have faith, but the beta clearly showed it needs quite a bit more baking to be even above average.
