Blizzard, back in the day, was willing to simply can games, even highly anticipated ones, when they didn’t meet their standards, even after a couple years of work. StarCraft: Nova, Lord of the Clans…

And Square-Enix managed to take an MMORPG that was already released, tear it down to bare bones and completely rebuild it to make it good, with FFXIV: A Realm Reborn.

So it is possible to completely redo something if it doesn’t work out…
