It's actually not random because computers can't actually generate random numbers.

but grats on the good luck streak either way.

Actually, there's a way around it. Functions that get the current time, can get it up to very small fractions of seconds. All you have to do is choose the last digit(s) as a random number. =) 

If the pattern repeats at any point, it is not be definition "random".

If the seed number feeds off, say, the number of seconds since "X" date, then that number will never be the same, creating a truly random number.

I could give you the algorithm and you still could got predict the outcome. I played a lot of online poker, this was always brought up.

When implemented properly, pseudo-random number generators are certainly a good enough approximation of true randomness for the purposes of the ME3 store.

The big question is if it's been implemented properly.

[GiroX-]

Any kind of number generator is going to have some sort of limit on the number in generates and it what form. That's being picky though and besides the point.

I've had an awesome lucky streak over the past week and a half. A little over 30 PSP's and I got 10 URs. Most of em were Volus character cards that I wont use much, but a 1:3 UR/Pack ratio has got to be the best I've gotten consistently in this game.

In mathematics/statistics, which is what we are dealing with here,

random = cannot predict outcome. 

random =/= no pattern. 

For example: Throw a dice, the outcome is random. Meaning you can't predict what the number you will get. However, the pattern is that roughly 16.67%  of the time you'll get a 1.

I'm sure Cyonan is aware of pseudo-random numbers generation mechanism. However, he is right that non of the number are truly random since if you know the random seed, you can readily predict the outcome. Approximation is one thing, precision is another.

Well said.

TLDR: Computers can't really generate random numbers, but they are pretty darn good at simulating it. Truth of the matter is it doesn't matter at all in a gaming context and anyone who feels the need to bring up the topic again is a wise-ass.

Working as intended.

[stysiaq]

damn, right before I wanted to quote the non-existent k1ngl1ves.

anyway, the thread should be renamed to "pseudorandom is a good approximation of a real random".

Technically true but for all we know the RNG for the store may in fact be tapped into a white-noise radio frequency or something similar to generate entropy




... granted, that's not very likely.
