Pros:
Storyline: Making another game using the same map within a few years apart in game was risky for the creators. It's nice to travel and see what change and villages that grew. But I also feel that they tried to erase BOTW storyline too much.
Overall: While it was risky to make another game with the same map, I do enjoy continuing my adventures around Hyrule and meeting new characters and challenges. There is a lot of work needing to be done however it's worth playing.
Cons:
Link's House: While getting Link's house in BOTW was just a side quest, I really felt like they kicked Link out of his house and down graded him. Pre-furniture blocks that you can move around. A DLC could fix this but that would be relocating his house to a different part of the map and giving him a "normal style house" not blocks.. This is my biggest disappointment of the creators.
Dying: TOTK is a lot harder to play vs BOTW. Even with stack of hearts you can still be one hit killed by low level creatures. I believe this can be fixed by creating a story, normal and hard level for the player to choose when starting a new game.
Overall: I have played a lot of Zelda games, TOTK is not in my top favorites however I believe that the game can still be saved with DLC and listening to the player's review. Hyrule Warriors that used the same map as well is better than totk.
