I guess pressing X to win is more engaging for some people?
EDIT: I should clarify instead of being snarky.
I get the fact that this game isn't for everyone. What I don't guy is saying that the combat system isn't engaging. You can not like it, sure, but I know every single person who has frquented this forum has played and loved RPGs where you literally can win without much trouble by selecting the fight command in RPGs (in most cases). That doesn't make those games bad, as I love those types of games as well.
I found trying to figure out how to engage the enemies peacefully always kept me on my toes. I also like how the game constantly threw new things at you. Most importantly, the game is exactly as long as it needs to be. No filler. No fluff. No grinding (unless you are a jerk, but that's the point in that case). Just a fun game with well written characters and story.
