Okay, so without delving into immediate spoilers...
I do find that many years ago, I often dreamed about SOTN having a much larger and more expansive map. Now that this has most certainly happened in ROTN , I find that as much as I had wanted a bigger castle to explore, this was perhaps not the best thing to ask for. I find the walks through the castle to take too long when needing to get somewhere, even with teleporting rooms available.
And well, then there are the bugs. Every time I die, the loading screen freezes and I have to restart the application. There are others for sure, but this is by far the most annoying thing in the game.
The first few bosses after the galleon were challenging, but after that I am agreeing with critics that simply refer to them as button-mashing-exchanging-of-blows. For the most part. I am only 50% map complete so far, so no idea if this will hold true.
I do like how the controls and movesets are identical to SOTN. I am not liking the sheer number of shards one needs to switch between to access skills that progress you through the dungeon--I wish it was all accessible via commands similar to SOTN in this regard, even with shortcuts, it can be annoying having to switch skills to go forward in the dungeon at times. SOTN had it perfectly nailed in this regard, it really negated the need for switching items on and off by having a great set of control pad commands.
Voice Acting : David Hayter does something special for MGS, but I don't feel anything great about him in this game.
Belgrade's character, great and funny.
I also like how every weapon is even more viable of a choice now. I used to love even the simple Jeweled gloves kung fu in SOTN, and am glad it is beefed up a bit more now.
