I got to play a bunch this weekend and I love this game. I don't play a ton of open world games nor RPGs, but I'm addicted to this one. I was relying on stealth a lot in the early game, so much so that I thought I was invincible. Then, without spoiling anything, I get trapped in a place with NO cover and a huge enemy. I now needed to learn how to fight something head on instantly and it was quite fun. Oh, I have traps I've never used before?!?!? Let's give those a whirl. Oh, what's this thing I picked up awhile ago and never used? It's getting equipped. Suddenly, after being ripped from my comfort zone, the whole game opened up to me and now I can go into situations doing things completely different.
Plus, it doesn't hurt that the game is gorgeous and I'm invested in the story.
