The way to attract or convert people to OP in general (or in my case Delphi), I know of only one.

They need to be shown from the beginning what ridiculously amazing things you can do with it, making games being probably the top attraction. I have been trying to get family members and friends interested, even in just programming or scripting in general but to not much success.

My brother is still fiddling with that darn object/scripting engine thing you get through steam (not sure what it's called), but the language looks reasonably complex and he is good at it, it's just a matter of getting him interested in building something from scratch instead of playing with someone else's toy lol.
