A handful of engines (mostly UE4) are used for the vast majority of *all* games. What does Unreal Tournament have to do with it? Some UE4 games aren't even first-person, some are things like RTS.

High-speed rail requires a 100-foot wide right of way for double tracks. It's not just about building over things, it's about not requiring the very wide right-of-way that high-speed rail requires.
1) No, but you're talking about acceleration rates (if it takes 100 miles to hit full speed) that are half that of a high speed train, despite not needing to carry your motors or power (for acceleration with you). There's no reason to be accelerating that slowly. Aircraft, as you point out, accelerate much faster, and passengers tolerate that just fine.
2) A full system would require that, as would a test track, but the article merely said they needed that much track to get to full speed. It didn't qualify if that included deceleration.
3) Except the hyper loop capsules are far smaller than high speed trains, and their acceleration rate would hit hyper loop speed in 50 miles. The hyper loop uses linear accelerators in the tubes themselves, so power isn't really an issue: you can accelerate the vehicle at whatever speed you want, passenger comfort is the limitation.
Also, the hyper loop is not equivalent to a train car on an elevated track. Because it's not a train, it's a ground effect aircraft in a partially evacuated tube. It makes no physical contact with the walls. If anything, it's closer to a maglev train than a regular train.
The hyperloop uses low pressure air because the design assumes there will always be lots of leaks, which can be overcome by the pumps. Air will always be leaking in, so you just pump it back out. And because it's not a vacuum, the pumps aren't as insane as they'd need to be to maintain a hard vacuum.
As soon as you start talking about putting anything but air in the thing, then that whole idea goes out the window, you now need to go from "mostly airtight" to "completely and utterly airtight", and everything gets incredibly difficult.
Sure, because the cost of materials has little to do with the cost of building a highspeed railway. You've got a mighty wide right of way, and you need to buy a huge amount of land for that, plus there's a ton of labour to prepare that right of way, clearing it of all obstacles, leveling the terrain, installing the track, the filler, etc.
The hyperloop could theoretically end up cheaper because it requires a smaller right of way with much less labour to install. The cost of materials would be higher, but the huge reduction in land requirements and labour could potentially counteract that.
Just because it's in TFA doesn't mean it's right. At the same maximum acceleration of a Tesla Model S (1g in "insane" mode), you need 3.6 miles to get up to full hyperloop speed. If you want to take 100 miles to do the same thing, you're talking about 0.04g, which is absurdly slow. That acceleration would give your car a 0 to 60 time of 75 seconds...
There's no need to accelerate that absurdly slow. Cars, airplanes, trains, they all accelerate much faster than that. On the other hand, if their 100 miles includes the distance required to decelerate...
As if the Canadian economy isn't hurting enough, now Obama's gotta go and twist the knife.
The fact that they were addons actually made them even bigger disasters. Because they required custom software, they behaved like they were standalone systems (a Sega CD game was useless to a purely Sega Genesis owner). But at the same time, the maximum possible market for the SegaCD was existing Genesis owners.
The Saturn was the biggest component of why the industry was pissed at Sega, but their scattershot console strategy leading up to the Saturn was definitely a factor on peoples minds.
Microsoft went in expecting the Xbox to fail. They knew perfectly well what they were doing, which was buying their way into a well established an entrenched market. The money they dumped into the original Xbox was the cost of entry, so obviously they knew what they were getting into.
The strategy worked, too. The Xbox 360 was a strong contender in the market, and captured nearly a third of a three-system market. Of course, they blew it this generation, but that doesn't say anything about their original strategy at the beginning.
Sega had problems getting developers for the Dreamcast long before there were any piracy problems. They alienated developers by spitting out new incompatible hardware in a rapidfire format. The 32X was released shortly before the Saturn, and then the Saturn was abandoned early into its lifespan in favour of the Dreamcast. Between 1991 and 1998, Sega had a total of five different and incompatible hardware platforms on the market, six if you include the GameGear.
By the time the Dreamcast rolled around, many developers had had enough of Sega's schizophrenic console strategy, and avoided them.
A 35 degree diagonal field of view isn't a virtual reality headset, it's a portable personal display. If the manufacturer is citing "equivalent to an X inch screen at a distance of Y feet away", then it's not for VR.
You're still moving that mass, regardless of how it's mounted on the head.
MP3 is a compression codec. OGG is a container format. MPEG-DASH is a standard for how to do bitrate-adaptive streaming over HTTP. They're all completely different things.
MPEG-DASH is codec-agnostic, and does not require or imply any specific codec. However, since it's intended for audiovisual streaming (rather than just audio), and since it's done under the auspices of the MPEG, h.264/AAC are the obvious codec pair to choose. There is nothing stopping MPEG-DASH from being used to stream something like VP8/Vorbis or VP9/Opus... and in fact the WebM project has documentation detailing exactly that.
They became obsolete when naval warfare stopped being about shelling things and started being about launching aircraft, missiles, and torpedoes. They haven't really been relevant since the second world war, and even then their utility was questionable: aircraft carriers dominated naval battles of the 1930s and 1940s. Nobody has built one in more than 70 years.
Betteridge says the likely answer is no. Looking at the article, there's a whole lot of predictions and guesses in there. LEDs and lasers? Water is very good at attenuating light, and even a ship directly on top of a submersed vessel wouldn't be able to detect anything using light... and coastal water attenuates light MUCH faster than open ocean, due to all the extra stuff in the water...
