They are obsessing but it could be worse, they could be beating a long dead horse, digging it up, beating it again, violating it in horribly graphic ways.... kinda like what's happened to Final Fantasy VII, at least XIII-2 was a decent game unlike DoC.
They're pushing the whole XIII thing but not to the point its destroying all that the fans hold sacred... like Final Fantasy VII... Since, not many people actually like XIII in the first place so there's really not that much damage done.

With me, I enjoyed XIII, the characters, eventually, the story, eventually- yes, I am serious here! D:
Were pretty damn good and I rate it along with IV VII VIII and XII as a favourite of mine, I really enjoyed Lightning as a character, she was a return to the type of hero Cloud and Squall were, just a lot less socially retarded throughout the game and ending up as soppy and cringeworthy shadows of what made them iconic at the start of the game.

I would take Lightning well over the likes of the happy go lucky cheese heroes you see in things like One Piece, I'm talking Zidane, Tidus and Vaan (if you dare consider him a hero XD)

So, someone here, is going to reply here, pick out my points, counter them and question me about them all triggering a quote pyramid war. WELL I KNOW, I have seen the future and the future is orange, derp...

Right er, back to the point. I don't mind another XIII, especially one based on Lightning. I still hold its sequel well above the whole prequel/sequel thing that was shot into FFVII but hey, I'm talking bollocks, there's no way anyone can not love and speak great good of a game as perfect and flawless in every way imaginable such as the flagship game of the entire FF series that is VII, riiiiiiiight?

Ok... Well, that was fun.
