1.) 25-26 hrs
2.) Yes, it’s worth it. The fast battle system is what kept me going and the story of course.The final battle was intense!
3.) You’ll get the true ending right after you finish the game. You unlock paradox endings after that.
4.) I’m not sure which DLC you are talking about. If you’re into costume DLCs, get it. The only DLC costume I’m interested in is Ezio’s costume. If it’s an episode continuation DLC, then yes i think it’s worth it since I, myself, am not satisfied with the ending.
