As much as I love franchise I just don't like the concept of switching playable characters back and forth and it seems it's even wrorse, because the game is divided into two sections where the first half of the game, lets say first 4h, we play mostly as Grace with stealth approach, and the second section, next half of the game, we play as Leon with action approach. So if you like only one type of gameplay then you don't enjoy (hate) the other part of the game, and vice versa. Moreover, you only have half of the game that you enjoy, which is very small, you cannot commit to just one character development etc. I would very much more like the approach where u can play the game from start to end with just one character and type of gameplay, and then you can start over with the other character. That would be much more fun I think, and would be better overall game experience for everyone in the end.
That's the only and very big reason I will rather wait for discount to play it.
