"principle of proportionality" - ever heard of that?
Addition works equally well for 2+2 and 200000000+200000000. In seeking the truth, we sometimes take abstractions from the small to the bigger picture, or the other way around. Sometimes it's successful, sometimes not.
There, however, needs be to a reason why it wouldn't work.
Does not the same principle of gravity work for both basketballs and planets?
To get back to this case, we're talking about whether you need to have experienced X to be able to make a valid point about X. You used it for a computer game. But if we replace it with, say, senators talking about the pay of senators, they are probably always going to say that they should be paid more. Or maybe with death, if you haven't experienced death, your opinions about death don't count. This makes no sense.
Maybe my comparison lacked tact and was inconsiderate, but nevertheless if the principle of "you need to have experienced X to be able to make a valid point about X" fails in one instance (or in a quite bit more), we should reconsider just how good a principle it is.
