Good.
FFXIII wasn't great, but that's not to say the effort wasn't there. It tried to introduce a new generation of gamers to Final Fantasy. Gaming has become a mainstream entertainment industry over the past few years and SE can't expect to please everyone. Certain "old school" fans cry out for remakes but I reckon that'd just be a horrible waste of resources. They operate a business and the only way to grow a business is to attract new customers. Remasters, direct sequels, mobile phone games aren't going to do anything for them.
Focus solely on a next-gen game. Make it a Game of the Year contender - a game that sets a new standard for RPGs, rather than rehashing old ideas.
