"Every game thrives on an element of surprise, that tantalizing unpredictability that hooks players in. But managing this randomness, these 'RNG needs', is often more art than science. With RNGNeeds, you have a Unity plugin that redefines randomness, transforming it from a wild variable into a finely-tuned instrument of creativity."

✨ Need to raise the odds of a critical strike based on player stats? Want to increase the chance of spawning that elite monster when it's close to midnight? Perhaps you need to drop health potions more often in tutorial scenarios.

"Beyond the dice rolls and item drops, RNGNeeds offers you a canvas of opportunity. Imagine dynamically adjusting the frequency of in-game storms as your player progresses through the storyline, modulating NPC behavior based on time of day, or making the battle more intense if the music volume is loud."
