At times I feel like I'm playing the old kings quest games where you had to pixel hunt and combine random items to make things work. A few puzzles I just have to brute force my way through since there wasn't a enough info on what you needed to to in the area. Sometimes I can't tell if stuff is just bugged. I know the there was one switch near the winter king that you have to be at just the right camera angle in order to hit it even once your perception spots is. The immaculate prison is another I have multiple prison keys for it, but none of the doors will open.
Just remember that when you finally find the candle and head down stairs to already have the hammer and stake with you so when you open the casket you can kill the vampire. Man those games were such a headache.
And you're right, this game reminds me of that a lot. Too many times I find myself running to the forums for help with some area, quests, puzzle. Sure the second time I play the game all will be fine, but this first time it's very frustrating. I wonder if the first time I played BG1 if it was like this. I replayed that game so many times that I just don't remember. I'm sure 10 years from now I'll think this game was just perfect also ... if I haven't croaked by then.
