They can be paused and unpaused (making them great for actual videogame scripting, like you'd script a scene in a movie), they work a lot like preemptive multitasking (which is a cool model imo), and they can be modularized quite easily

Like, my original plan for a game engine was a system where you load up an "infinite map", and you set up "systems" and "scripts":

• systems would operate under everything that meets certain conditions, such as, if it's in the water and can float, then it must be given the effect of buyoancy
• scripts would act like actual scripts, like movie scripts, where characters can be scripted to talk, have animations, listen to player inputs, etc.

I'm calling this project Flowerpot: A Starlight Network Project
