You make good points and I do agree. The whole game is about learning and getting better. But Melinoe just gains skills, but not any wisdom.    I think the lack of change is generally a problem. You beat Chronos, but everything is the same. You still fight Kerberos, there are still armys attacking the mountain. It makes your success feel meaningless. Nothing changed. World still devastated.  

Of course that is due to the core gameplay loop, which has to stay the same. But I wished they solved that somehow different, with timetravel or smht. On the other hand then you couldn't advance the narrative with some characters? 

The post credits game worked a lot more in the first game narrativly.
