RPG Engine Toolkit Tech Demo (feedback needed)

This look’s really interesting and I am deffo going to buy it soon, however I do have a few questions, since I am new to UE and don’t have alot of coding experience yet.

  1. Can I make a playable game with this engine without having to modify alot?
  2. Are the graphics easy to be changed? (Graphics of mini map for example).
  3. Can this be added to a existing project?

Those are the two main questions I have before I buy this package. As for the rest, very good job! Looks amazing.
