This is outstanding and deserving of nothing less than a Highly Recommended.
Could you please post the triggers in the description though? :3
edit
Seriously, if you can improve the triggers, I'd nag Bribe to rate it 5/5 =P (It's not always about the triggers, but sometimes, the concept)
1- Instead of making it run specifically for Player 1, you should give it the ability to run for multiple players.
2- In the Conversation NCD trigger, the wait can be removed
3- This should also be able to support multiple units per player :/ (Since this system is going to be used for RPG maps only, I'm guessing a unit array variable supporting one unit per player would be fine. You could take it a step further and give it support for multiple units. )
4- Instead of 0.02, use 0.03 for the periodic trigger
5- All the variables like Conversation and the like should be arrays so that it could support multiple players.
Yes, I still rated it 5/5 even though the triggers needed an improvement.
Is there a problem? I loved it.
