I actually had the opposite opinion. I thought CBU3 was better at making MMOs than single player games. Not saying FFXIV is great, but between the two I would rather play FFXIV than FFXVI. Considering 16 has a lot of elements from FFXIV, it reinforced my opinion that it doesn't work for a single player game. Linear dungeons was one thing for an MMO, but for a single player too? That draws a line for me.
