My point is that if you buy games based upon their pitch, eventually you're going to get burned. Now, obviously, it's his money and he can do whatever he likes with it, all I'm saying is that waiting until there is critique out there hurts nothing. In a world of digital codes, there's not going to be a shortage of the game he wants to buy. In the past five years, I've pre-ordered two games: BioShock Infinite and Skyrim, based upon my enjoyment of previous titles and anticipation of what I expected those games to be. While I ultimately would do it again for BSI, I got bored after reaching level ten and quit Skyrim; it wasn't worth my time nor money. I'm rambling, but what I'm essentially trying to say is this: my personal stance on pre-orderes is that if I have enjoyed at least one previous title in the series and very much need to play it right fucking now, fine, I'll pre-order it. Otherwise? I'll wait at least 24 hours and see what's good and bad about it. The wait won't kill me, and I'll be informed of what, if anything, plagues the game. I feel like pre-ordering is an emotional "gotta have it now" response, while waiting a day and assessing what the game turned out to be is the logical response.
What is a review? My link is most certainly not a review. In the broad sense, you can call it whatever you'd like, but TB is very clear that/when he doesn't finish the game (which is very often). "My Initial Thoughts on Civilization 6" is a video he put out a month ago, for example. That's very clearly a first impression, not a "finished" review. For his "WTF Is... - Shadow Warrior 2?" video he put out three weeks ago, he shows, and explicitly says, that he's finished ~30% (it's been three months since I've seen it, I can't recall how long exactly) of the game, and says multiple times "this may improve later down the line, but as it stands now, X sucks", etc. That, to me, aligns more towards first impressions, not reviews. In regards to NMS, I'm fairly certain TB has been negative towards the game, and he usually plays a good chunk of the game before putting his thoughts out there. Putting out his thoughts on the first "1-3 hours" of a game means very little.
Of course two tweets don't cover the entire scope of three platforms with a multitude of different configurations, that would be silly to argue. I find it to be a reasonable stance to say "at 'medium' settings, there are significant problems. Be wary of this game". Do you? Normally, when he gives more detailed information specs in a video, he tests on low, medium, and high for PC. A tweet is not his video. I'm sure that will be forthcoming. He is known for the PC platform, it would be rather strange to cover a platform he - as well as his audience, I'd venture to guess - has little to no interest in. Would I prefer information on every device? Sure, but I don't expect that of him.
I like him, so I can't speak in regards to those that don't, however short of his "get cancer and die" tweet, I am honestly ignorant of his assholeishness. How his fans act shouldn't influence your perception of him, considering he isn't ordering nor endorsing this behavior. That's fine if you don't like him, we all have our likes and dislikes, I just can't say that I agree with you.
You have a point with getting certain expectations, but I don't think you do in regards to the rest of it - at least, not in how I use reviews. When I look at reviews, when I hear "the combat in Skyrim sucks!" (with no information as to why), that is a near meaningless thought that I dismiss. However, when I hear "the combat in Skyrim sucks because X, Y, and Z", that is a meaningful thought that I do put value in. In TB's case, I find that his opinions usually fall into the latter category, so that regardless of if I've played a game or not, I can look at it and say "huh, that sounds like the combat is pretty shallow and disappointing... maybe I'll look for another game, where I'll find more fufilling gameplay". Obviously I don't expect you to draw the same conclusions that he does, but I feel that if you listen and entertain the reasoning behind his opinions, you can draw worthwhile thoughts about the game in question. This, I feel, is worthwhile and valuable.
