I was wondering what to expect since seeing this thread the first time, never read it until I completed it just now and I have some mixed thoughts, those being I understand why some people may have been frustrated with it, and why others may have liked it.
I kinda liked it because I felt powerless as hell, I knew I could kill some enemies, but how many? I like to stealth in games as it is and this one tested my patience with unscripted AI movement, I was being patient waiting till the enemies gave me a path to walk though, and funnily enough I ran the wrong way to start off with, but I found a bunch of medkits to use if things went south which made me feel a little confident, I found the wounded imperial soldier, went all the way back for the key again so I basically ran the map at least twice and managed to avoid combat entirely with a tiny bit of luck in some bits due to impatience on waiting for the AI to move again just to make sure I don't enter combat.
After all that though it's a straight forward combat scenario which actually had me worried due to the strength of the enemies and seeing the armed civilians getting low and some dying around me, the last bit with the explosion had me "wtf" for a second because I couldn't tell if I actually dead and had to restart but turns out its part of the story.
So all in all what with how many medkits they give you and some patience this should be do-able with what I would of assumed 2 tries on average, maybe 3 if you're somehow really unlucky or just very impatient, some people saying they felt betrayed on the story with how it was being told are being overly dramatic and honestly it just shows how easy people have come to expect their games as times have progressed, 1 failure or a little bit of actual difficultyand suddenly "the game sucks" or something, I've always found it amusing how you can go through this games entire story with literally 0 challenge at all, I wouldn't dare half the people here to pick up a sega/snes pad and play something like Lion King, Earthworm Jim, Alladin etc, or ps1 games like command and conquer if you truely want to see what hard is lol, or hell just go and play Dark Souls.
