FFXV Episode Duscae Version 2.0 is a definite improvement over the first version. Like sephy says the combat is faster, and I'm liking the addition of Chain Links (group attacks). Also the Arminger is much flashier now! When you use it and you warp towards an enemy things get crazy! I love it

I'm liking the "On Tour" quests as well, where after camping at certain times you have the choice to go out with just Noctis and one of the others to fulfill a certain requirement.

Honestly this is probably the best demo that I have ever played, and I can't wait to finally be able to play the full game with all the features intact!
