Uh, so what makes stealth fun is uh - it's the proximity to danger. So, and that - that's also good for action games. But, basically, the closest you are to a source of danger, and if it's a threat of you know, dying for example, the more adrenaline you are going to get. So, two people face each other. And, you're like, okay. Somebody's going to - excitement jumps. So, the fact that on stealth you can recreate that. And, keep it - you can create suspense with it. Because, you are going to be really close to danger. And, can be really, really close for a long time. That's not going to happen in an action game. So, if you master this, you can become the Hitchcock of - of video games. The longer, or the more you can create those scenarios. Where, I'm extremely close of failing. I'm going to fail like this. Super close. And, I'm in directing the closest to that source, it's - it's impossible not to be an incredibly addictive experience, because you're just - it's just full of adrenaline. In a context where you need to control yourself also. So, there is a lot of tension. You're like, ahh, I want to - I want to remove that danger. But, I'm stuck with it. So - so, a good stealth game can generate all those emotions.
