Maybe you can help me a bit. With Mario, the gameplay element is jumping. When you jump on different objects or enemy types they react differently. Jumping on a Koopa is different than jumping on a Goomba and so on. These reactions are arranged into an amazing and creative game. With Splatoon, the gameplay element is team based ink coverage. Each weapon has a different take on such a task. Different modes provide additional twists on this idea of covering the world with ink. It is this varied, yet easy to understand concepts by what I mean by gameplay first.
Bloodborne, and I know I'm judging a game by its title, sounds like something where you get weapons and kill things. Sometimes there are things that are harder to kill. But the concept is the same. Get weapon, kill things, move. Get weapon, kill things. move. Just like Space Invaders. Kill thing and move isn't something that interest me. Perhaps you can help me understand how Bloodborne should be in my library. I just don't see me bringing it home and saying, "Hey kids! Let's sit around the PS4 and play Bloodborne!" or "Guys, want to come over to my house after work?" "To play Smash!?" "No to 'Bloodborne' it up!" Please convince me on what I'm missing.
You get what I'm saying? I'm sure Bloodborne and games like it are challenging and entertaining to a certain group of gamers, but not for me. So if I don't get excited about the next "mash 'x' and kill things" games, don't worry. I'll still support the PS4 by buying games like 'Dragon Quest Builders'.
