XIII, XIII-2 and LR:XIII are three completely different games, gameplay-wise. This one is the least like the others. It all depends on what you consider most important when you play the game, but I'm having a lot of fun. This game is sort of like a sandbox/themepark game. I think 5/10 is very harsh, personally, but everyone has the right to decide for themselves. I wouldn't expect XIII-haters to suddenly like the characters or the story, which means they probably won't like the game because it is a major part of it. If you didn't have any real issue with the story/characters in the earlier games, then I think there's every chance you'll find this game quite enjoyable.

I also agree with what Seph mentioned - by day three I could extend time massively, by day four I could extend time near-endlessly.
