What kind of random number generator is the custom engine running for gold drops?
My guess would be linear congruential generator because the randomness of most gold drops is within a believable range even with pseudo-randomness. It's possible Blizzard is implementing a Mersenne twister to make up for flaws in an LCG, but it would seem unnecessary and it would probably take longer to generate the numbers. These two generators are probably the most common types. Can I get an answer for educational purposes?
