I know there's one or two already out there, which I haven't taken a look at yet. What use would you have for a script that lets you spawn (reasonably) unlimited events that will last until you leave the current map? You could use it for things like cutscenes where you want blank events for NPCs that will be controlled by a "master" event, but for that, it's already easy enough to just add blank events to the map. The best use I can think of is for something like a shooter or tower-defense type minigame/puzzle, or a dungeon where monsters just keep coming after you. What other things could you do with it?
