XV had its faults but I spent hours and hours on it. I bought XIII twice (PS3 and PC) and while characterization is still shit on PC I got a bit further there (about 12 hours) vs PS3 because VA is horrific.
I will take XV's bugs and issues any time over whatever the hell XIII tried to do and utterly fail. At least 4 main characters were fairly likeable on XV. I hated every single character in XIII except for perhaps Sazh.
And let's not forget the "tunnel vision". I will take beautiful if a a bit repetitive first half of XV over XIII. That's for sure.
Edit: XIII characters, writing and VA got me mad just thinking about that game again. Even Japanese VA did t help past certain point.
It wasn't even really the characters or the voices. FFXIII's writing was just very decidedly "Anime". It was just atrocious for the kind of story that it was going for.
Far more "Kingdom Hearts" than "Final Fantasy", and this was especially jarring coming off of Final Fantasy XII.
The setting was particularly odd too, as far as Final Fantasy games go. The monster designs were overly
abstract, and not in a "Midgar Slums Transforming House" way. It's more of a "we're implying that these are practical creature designs within the universe of XIII but we're going to make no attempt to explain how or why."
So much about the series just rubbed me the wrong way. I could have forgiven the corridor level design and shallow combat flow if only the story and setting felt believable, but it just
didn't.
That's really my biggest problem with FFXIII. Everything in that game was far too hard to swallow. The dialogue, the setting, the lore, the world, the people, their ambitions, everything was just....eugh. Every design and writing decision in that game just felt
forced somehow.
Not to mention how after XIII, they just desperately tried to shove Lighting down your throat, to the point of retconning her personality once in FFXIII-2, and then making a completely different character in XIII-3
