  1. Re:Flow "theory"? uh... DUH! on Play PS3 Title flOw Right Now · · Score: 1

    From my reading, the "innovation" is supposed to come in tuning the game's difficulty automatically to the user's performance, not merely the idea that a game should be between "frustrating" and "boring".

    This can be a good idea, but it's worth pointing out it's not new at all. I recently started in on a task that I've had planned for a while working on the same basic idea, only applied to a learning program (can't even call it a "game"): Dynamically deciding which new concepts to introduce when, depending on how well and how quickly the user has mastered the previous concepts. The only odd thing is how few "learning" programs use this idea. It's not a new one.

    In gaming, the idea is older than many Slashdot posters. While I wouldn't be surprised somebody can pull out an Atari 2600 game that uses the same principles, I can name the Intellivision game, Astrosmash as using the same basic idea. As you do better, the game gets more difficult. As you do work, the game gets easier. It very naturally slots into a difficulty level that can suck you in for hours. (It is probably a good thing nobody has really studied how to make an addictive game deliberately, excepting maybe the MMORPG people although I still that that's accidental; it would probably be surprisingly easy to make a truly addictive game if you tried.) I played this just a couple of years ago and it was even in the PS2 era capable of being quite addicting, because the game never ended.

    Follow the link; there is a funny story on the bottom about the accidental combination of some Intellivision features and limitations, a scoring contest for money, and the fact that it's essentially impossible to lose a game of Astrosmash even for a complete novice.

    Right now, probably nobody really knows. The game devs and their testers are too close to the game to know whether it is any actual fun, and almost all of our reviewers have at most a few hours experience, all in the same day.

    My wife wanted to get a DS (w00t!) just for Brain Age and Big Brain Academy, which she played at a friends briefly.

    She initially liked Brain Age better, as did I, but Big Brain Academy has aged better.

    It feels less stupid. Brain Age is true to its goal of trying to keep your brain alert, but many of the challenges only make sense in that context. If you're not in to things where the computer just sits there and watches you do it, like making you draw a picture but being completely unable to grade it, you won't like it as well. In Big Brain Academy everything is actually evaluated.

    Also, in Big Brain Academy, while we like some challenges more than others, we pretty much like them all. Leave it to a psychologist to decide to write a test that uses the same parts of the brain as the Stroop test, and actually implements... the Stroop color test directly. Look, when we say games "test reaction time", we don't do it by having every "game" consist of pressing the button as quickly as possible when the light goes on. We have a game where reaction time is smoothly integrated into the rest of the game. Surely we could have done something Stroop-like, without being basically a video-game transcription of a rather dull psychological test.

    I don't regret getting Brain Age because some of its tests are valuable. I intend to work with the word list memorization one more, for instance. But I plan on using the cheat code to allow myself to pick it deliberately and skip the Stroop testing.

    His science is far from "stellar". Often, it's quite poor.
    "Science" here has two basic meanings.

    What is science? The distinguishing characteristic is that it comes as close as possible to the ideal of "gather data - hypothesize - test hypothesis" feedback loop as possible. There are some additional useful criteria, like using controls, etc., but the feedback loop is the basic element of science.

    By this criteria, this is nearly the most scientific show on television, and they've gotten better in the past couple of seasons too. For actually showing the scientific process, I can forgive much.

    (The process may not always be perfect, but news flash: If you think every peer-reviewed study has perfect, impeccable controls and rock-solid statistics and complete coverage of the relevant topics, you're on crack. Real experiments often look uncomfortably like a Mythbusters production. No fair holding Mythbusters to semi-mythical ideals when "real" scientists generally don't make it either.)

    The other aspect of science is the large body of knowledge and experience that has been built up by the human race by the repeated application of that feedback loop. Sometimes they do OK, sometimes they do poorly; the farther they stray from application of mechanical principles, the worse they tend to do. (On the other hand, they sometimes surprise me; IIRC, they pointed out that sharp pointy things attract lightning better than flat things in one of the lightning episodes, which is something I only covered in calc-based electromagnetism in college and I daresay most people have never been exposed to.)

    Yes, they aren't perfect in this department. However, I'm not sure it's possible for them to be perfect. First, I've seen a lot of so-called criticisms that are more wrong than the show is, so for those people even if the show actually improved, they'll believe it's getting worse. Second, by its very nature, it covers an extremely large array of topics, and you're just not going to be able to put together a team of experts in chemistry (all kinds), physics (any kind you'd encounter in normal life), psychology (all kinds), history (all kinds, including the actual building of historical devices), and random misc. (all kinds), and still be able to afford to put it on TV.

    Personally, I think they're better than nothing, and doing a decent job, all things considered.

    Could they be better in theory? Certainly! Could you get much better in practice? That's much less clear. It's not fair to compare Mythbusters to the show that exists in your head that has an infinite budget and unlimited access to the best experts of all kinds. That's not an alternative.

The fact that this has other implications is not lost on me; the page I linked to explicitly calls out "two friends watching a DVD" vs. "one friend giving a copy of the DVD to his friend which he watches once" as an example of a situation that already exists where my model says the same thing happened, but the current legal model is that one was legal and one was not.

    In summation, I assert that a computer shouldn't have any legal or ethical standing anyhow, so who cares how many copies a computer makes of something? What matters is human experience. Under my model, "piracy" (skip the word debates, please) is not the act of downloading something, it's the act of actually viewing/hearing it. If you download something and immediately delete it, it's not piracy.

    (Note that this is really necessary anyhow; suppose you download something claiming to be public domain, yet you discover it's actually last year's top movie, and delete it immediately upon discovering that. You really shouldn't be charged with piracy. Under the law today, you are.
