They cannot think "oh this game will make profit in 4, 5, 6, latest of 8 years from now". They think "this is loosing money you have xxx amount of time to fix it or we will pull the plug"
If they dropped FFXIV in Dec 2010 they could have made alot more profit than the millions in losses from FFXIV alone, they are sticking with FFXIV because FF is the flagship franchise for SE, pretty much they let FF fail they will start to loose alot of money, imagine if Nintendo dropped Mario, that would be alot of money and games gone.
And your mention of FFXIII-2 being a $3 reskin is just plain stupid, its a damn sequil to XIII, of course alot will be the same, did you say the last 2 matrix movies sucked because they had the same characters and locations.
Or Super Mario on the Wii, blatent reskin of the origanal NES ones NINTENDO DONT CARE ABOUT MARIO!!!!!!!
A couple of examples why you would be affected if they put an IQ limit on the internet.
And yes I do have 10 IQ points to spare, you however dont.
