Hey guys I'm still here! Event systems are fun and easier to customize than scripts! Plus they don't have game-breaking bugs!
I like game breaking bugs. At least you know what - in most cases - is going wrong. Event systems, if not done carefully, can introduce lots of hard to track bugs. I always need a pen and paper for eventing things whereas a script I can usually figure out bugs without.
Also, I agree with Pacman. I also think they are easier to customise if the configurable options are presented well.
Well, it's easier to pop onto a forum and request a script than it is to actually figure out how to event a lot of things, now, isn't it?
Even a script with a lot of customizable options is easy to paste into the editor and set up than following a tutorial and doing the eventing yourself. Even if you handed over a project where you could copy/paste the events, if the variables or switches or other bits clash with your own project, there is an awful lot of trouble in finding and changing the specifics. With a script you can, if so desired, have one line that provides a range of free variables/switch ids that can be used. This is the reason why RMRK used to mark certain tutorials with a kind of mark of approval because it fit to a standard and all of the systems could have been used together with no clashes whatsoever.
This does make for something worthwhile to include in your opening post of requirements for an evented system: which variables/switches etc are available for use. Then you can at least reduce the specific requestee's troubles.
