I don't think criticizing FFXIII makes you a SquareEnix hater per-se, it's simply that this particular installment wasn't a lot of people's cup of tea. Every FF has been derisive for the most part (started with V as far as I remember).
No secret that I disliked XIII and liked FFXIII-2, but even that game had it's criticisms like any title. XIII-2 fixed a lot issues I had with XIII, yes they did in a "check off" fashion but they did it nonetheless:
____
+I like how they furthered improved upon the battle system and streamlined it.
+I really dug the Historia Crux mechanic and how it allowed you to replay scenarios with
different options if you so chose to. I also liked that many of the environments didn't feel as constricted as the original.
+I absolutely adored the OST for this game, very different and experimental. Wish they didn't take out the vocals for Invisible Invaders though.
+I enjoyed the overall cast much more than the original, Noel and Caius in particular however Serah was serviceable.
+I liked the Pokemon'ish third party member deal they had going.
+Aesthetically I thought the game looked great but then again I don't really care about reused assets and while good performance is always welcome, the game didn't crash so I'm" good.
+One of the most important things was how surprisingly quirky it was. FFXIII didn't have much of that at all.
-Battles for the most part were easy and I wish the Bleed mechanic played a more prominent role in battle; that could've been a goldmine as far as challenging the player and adding an extra layer to combat.
-The plot left a lot to be desired and borderline nonsensical, it felt like they were trying to do a reset and a sequel at the same time and using the paradox deal as a copout for both story design and choice making. Everything in the game feels inconsequential.
-Chocolina, I know what they were going for but the execution just didn't hit it.
-I wish Serendipity was more fleshed out as a lot of the games just didn't hold my attention for long.
-Performance issues; this isn't necessarily a thing for me like I said but it does hampers others ability to enjoy the game.
I could have someone just as easily strike down all of my positive points but at the end of the day if you enjoyed the game you enjoyed it. Hopefully LR turns out satisfactory.
