In terms of hardcore RPG, Bloodborne is by far the simplest.The game is just hard.Takes time and patience to get good at the game, but it isnt complex.
The Witcher 3 is more complex however.I personally dont find the item management, inventory and so on complex, but if you are not much of a fan of the genre to begin with, it may be overwhelming for you.And yes the game is long.Expect around 70 hours just to go through the campain with minimal sidequesting.
Try Bloodborne.As long as you are a patient guy, the game is almost a masterpiece.Just hope that story is not important to you, because it sucks, thought the atmosphere is great.Do give it a try
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
