Random Number Generator
Some of you might not know what that even means. Well, basically, in every single video game, there is part of the code that generates numbers "randomly"(a Random Number Generator, or RNG for short). This area is called by the parts of the game for whatever they are to be used for. These numbers go back to the other parts of the game and are used for damage, stats, levels, and pretty much everything. Well, when you are playing a pokemon game, the random number generator isn't so random. You can manipulate it to produce certain stats, natures, or pretty much whatever you want. Hopefully these guides will enlighten you should you be wanting to know what RNG is all about.
