Well, first of all, I have not pulled a Mobvok and read tons of commentary or watched hours of youtube clips about the game. I've read nothing, actually, including the spoilered comments in this thread. So, I kinda just let it marinate in my head and 24 hours or so later, I guess I know how I feel and what I think.
For starters, I liked it a lot overall and sometimes loved it. I...appreciate what the game was going for, and wish we lived in a world where the game could have been 100% what the creators likely wanted it to be, as opposed to a combination of their vision and the things you need in a game today to make it more universally appealing. I guess I'm saying that the combat felt.....like an afterthought....a cool afterthought, but an afterthought nontheless. What I loved was the look and feel....it felt authentic, odd as that word might be in this case...but it did....world felt real, lived in, etc....I loved just looking around, staring at the posters or statues, etc. I loved Elizabeth and her story, her reactions to the violence and the world around her, etc. Sidekicks usually annoy me, and they usually impede at times, etc...but she was well done and more of a help than anything else.
As for the game's final point....I was made to understand beforehand that the end was somewhat controversial, and perhaps left some items up for debate? I didn't find it all that confusing or ambiguous...but I also am not the most analytical game player, so perhaps I'm simplifying. I simply took the game's ending sequence as a commentary on gameplay itself...and the choices made within. I suppose some people might say it was a commentary on choice itself, but I don't think it was, and if it was, it falls a little short (and defies my personal beliefs)...but if it was simply a commentary on choices within the gaming world, then it hits its mark and then some. I took all the lighthouses to be both all the choices DeWitt did or did not make, his alternate realities...but also as a representation of everyone playing the game, how we all make our few choices but wind up in the same place. I thought DeWitt actually being Comstock was cool albeit not shocking so that was fine. I am a simple guy so I have a simple view, I guess. I'm sure the ending was more complex than I see it.
So those are my simple thoughts on the game. I am glad I played and wish I had a deeper analysis for you lot. I killed many crowmen but in the end, they wormed their way into my head so they won, really, not me.
