        I'm going to use D&D as an example.
        
        1 consecutive rolls of "1" -- 1 in 20
        2 consecutive rolls -- 1 in 400
        3 consecutive rolls -- 1 in 8000
        4 consecutive rolls -- 1 in 160000
        5 consecutive rolls -- 1 in 3200000
        6 consecutive rolls -- 1 in 64000000
        7 consecutive rolls -- 1 in 1280000000
        8 consecutive rolls -- 1 in 25600000000
        9 consecutive rolls -- 1 in 512000000000
        10 consecutive rolls -- 1 in 10240000000000
        
        To put it in Risk terms...
        
        If I attack 6 on 3 once and lose, I'm likely to complain a little,
        but write it off as chance. If I fail twice, I'm likely to complain
        a little and write it off as chance. If I fail 20 turns in a row,
        then I probably have a valid complaint -- either your dice are
        rigged or you are impossibly lucky.
        
        If every time I play with you the fights go like this, I'm going to
        believe strongly the dice are rigged. If every time I play, you are
        impossibly lucky, the simplest explanation is that you are cheating.
        And so, I will call you on it.
        
        If a player is complaining, it makes a lot of sense to look at the
        problem. It makes a lot of sense to look at logs and perform log
        analysis, and to determine if the complaint is valid or not.
        
        The C PRNG is a LCG. If you don't replace it with your own
        generator, it is useful for only short series of numbers before it
        starts having cycles and streaks. There are a lot better
        generators, even PRNG, out there -- ones that are many times better
        than the C one, and any good book on Computer Simulations will have
        code for several, including the C one, and an explanation of their
        strengths and weaknesses.
        
        The C PRNG can be made worse by using modulus to scale results. You
        can only properly scale results with a multiply followed by a
        divide, assuming integer math. Any other technique, particularly
        modulus, skews the results. Lets say the maximum number the LCG can
        generate is 32767. If you modulus that by 100, you'll see that 68
        through 99 occur less frequently than 0 through 67. If you modulus
        by 1000, 768 through 999 occur less frequently, and if you modulus
        by 10000, 2868 through 10000 occur less frequently.
        
        Assuming low rolls are bad (they generally are in most systems), if
        you are using the modulus operator you're skewing results towards
        failures.
        
        If you show me the results of the rolls, then you have to be
        confident there isn't actually a problem, because if I perceive a
        problem, the first thing I'm going to do is run the logs through an
        analyzer and see what numbers come out. In the most probably case,
        I'll find out there really is a skew, and I'll proceed to post it on
        a web site and it will become a much bigger issue than if it had
        been owned up to in the first place, especially on a large game.
