Sure. I think personally it cheapens the game for whoever is playing it. As an example, some video popped into my YouTube feed of someone doing something in one of the Hitman 3 levels. I don’t care to say who posted it as that isn’t the point. The subject though was that there was a way to get around a particular NPC reliably without being seen.
The method in question was basically to shoot the wall a few times, which caused this NPC to go where the bullet hit and investigate. Now the player in this video, after shooting the wall, walks basically right up to the NPC in clear view of him and of course the NPC never sees him because of the “bullet trick”.
The point of the video is clearly that by using this trick, you can avoid being seen by the NPC and thus maintain a Silent Assassin rating. My objection to the method is that the player didn’t avoid being seen, really. They used an AI glitch or exploit to do something they shouldn’t have been able to do.
I have gotten around that same NPC myself via at least two other methods. One involved simply killing the NPC and the other involved just not being seen but neither used a trick to do it. The fact that I found that particular method of avoiding this NPC “cheap” is what prompted me to expound in the first place.
Now having said all that, I don’t really care if YOU use a trick to complete the level in 2 seconds or get around some NPC or get whatever rating on every level doing it. I simply think that it makes the game “cheaper” to use those methods. I don’t use them but it doesn’t actually affect me if you do.
As for why I didn’t simply say “I think…” without any detail, I don’t prefer to post things like that unless I’m just replying to someone and it doesn’t require any additional detail.
I do know that the developers enjoy seeing things like this as it highlights to them areas where they could either improve their AI, repair glitches that they never intended, or they just like to see people “break” the game engine in entertaining ways.
You also pointed out that this is a single player game and therefore the way others play doesn’t make any difference. I agree with that wholeheartedly. I have been fairly vocal on this forum about stressing that I don’t bother with leader boards, or obsessing over getting a perfect 5-star rating, and I have never and will never post videos of my own game play. That said, there are people who do very much care how others play. There are threads on this forum about playing without using instinct, maps, or any other HUD elements. Those players probably don’t really care how anyone else plays the game either, but we encourage them to say what they think anyway.
