Czuch: I highly doubt that the dice are unfair. To make them so would require a lot of code. Plus Fencer probably has better ways to repercuss those he does not favor!

However, I would surmise that the dice are not random! After all, it's pretty hard to get a computer, which is designed to do the same thing exactly the same way every single time, to do something repeatedly and get a different result.

But I would guess that they are pretty close. ;-)

I'm sure they are close enough that it would take some serious statistical analysis to prove otherwise.

And even if there is an advantage or disadvantage to the dice, either players is probably just as likely to receive whatever benefit there is, so I believe the game here is fair.
