I think many people are saying its useless because it was a random youtuber. If say, a reputable media outlet such as IGN, Gamespot, GB etc were to release their playthough on the internet, all of a sudden people would sit up and take notice.
I guess we'll see how useless this current info is in a few days when the embargo drops.
I know you are just saying what other people think and not necessarily your opinion, but that is preposterous.
I myself have not seen that playthrough, so what I am about to say is subject to that disclaimer. But the people who HAVE seen it claim on here this player wasn't speedrunning or otherwise trying to fly through the game. On the flip side, he also wasn't playing like a completionist and thoroughly exploring every inch of the game. He just played it like most people would, taking his time dilly dallying here and there, screwing up and dying every so often, etc.
And he finished in under 6 hours.
What is there to consider "useless" about that? You can check out the video yourself I guess (I take the people who have seen it at their word) and if there is something others are leaving out that somehow made his playthrough much shorter than most will experience, please let me know what that is.
But outside of that, we apparently have video evidence of someone casually playing through the game in under 6 hours. That isn't some condemnation, it may very be a 10 out of 10 six hours of gameplay. But this weird denial of how long the game is seems to ignore actual video evidence, at least that's how I am understanding it.
