Random Magic Paths - is it truly random?

Oh I quite disagree; it doesn't take long to realize. Examples of incredibly poor games: Disciples II: The hit percentages never worked well. Most notably paralyziation; you would frequently hit 10 in a row, and then miss 10 in a row. Warlords IV: A low combat creature is fighting a high combat creature and the weaker hits, nearly every time the high combat creature would then miss his next attack. Odd behavior like that is hard to miss.

I'm not familiar with those games, but generall I doubt that you can distinguish RNG problem from the bug in the code. For example, Dom2 had a bug with mind duel, where it was OE D6 instead of simple D6. By monitoring statistics you could have thought that the problem is in RNG.

The use of the term pseudo-random is pointless; there is no randomness in our universe. None. It is similar to when people argue that everything humans do is also natural because we are natural; the term becomes meaningless by its own definition.

By 'poor' I simply mean they simulate statistical results with less accuracy than one would expect. Perhaps I should say: 'less accuracy than I would expect', since you seem to be argumentative.

RNG are not designed to simulate statistical results. They're simulating stochastic processes. Statistics are result of observation of the stochastic process. Any statistics resulting from the observation of stochastic process is a stochastic process itself. That's what make it hard to make reliable conclusions about stochastic process from the statistics.

Consider the original post with those dwarven smiths. Assuming that randoms are uniformly distributed, probability that 2 particular paths won't appear in a sequence of 14 smiths is (6/8)^14 = 0.0178. There 7+6+...+1 = 28 different pairs of 2 paths. So probability of not getting some 2 paths in a sequence of 14 smiths is 0.0178*28=0.4989. Just about like flipping that famous two-sided coin. So the examples that the poster has shown falls well within expected results. So after doing these calculations, original example looks like: "I've flipped coin and got tails 4 times in a row. Is it a buggy coin or am I missing something?" Now consider that there're few hundreds people playing Dominions here (some of them are quite familiar with probability theory, so we exclude them from this consideration) who do our "flips". It is very probable that few of them will get quite a few tails in a row. So one of them has posted his question (remember that in the actual case it is not immediately obvious that the probability of that outcome is 50%)

Perhaps that was not meant as a flame against my intelligence, but it sure sounded like it.

It was meant to question your knowledge of probability theory. You've jumped on Bummer_Duck hyphotesis/question claiming absolute knowledge (please reread your post) without any kind of backing. On top of that after closer examination Bummer_Duck's example is likely to be observed with ideal RNG. Of course, that doesn't prove that there's no problems with RNG, but this test, it passes very well.

Btw, I've noticed that you were not losing time meanwhile and have expanded your knowledge from over a half of PC games to the whole universe
