You're disappointing me I've tried my best to write that... and spent much time, effort and imagination... I thought it should be interesting for people out there. Probably I was mistaken.

First, I dont understand why Zhuinden says that your system shows the text to everyone, cause it's not.

Second, I dont understand the point of wait in Ahli's triggers.

The third... well, I just ask you, probably it will get you interested.

Have you thought about such situations when one player is allied to another and that another is not allied with the first? In what particular situations do you think the message should be displayed? Should the message be displayed if the exp has changed his owner (both are your enemies) in case that there was not a moment when your foes have broght 0 buildings?

The notion of nonsymmetry of ally relation have an interesting consequences which I am discussing. Ideas of new maps could be based on these property.

On the topic, I found Ahli's method quite interesting and have shown the particular situation when your and his system are working differently.

The wait in Ahlis triggers is supposed to wait with setting the switch until all players have received their message. Keep in mind first are ALL triggers of P1 checked, then ALL of P2, etc.

Scwiz's solution does not display it to ALL players, but to ALL players that are not allied to the one taking the expo (and thus can't see themselves) which should suffice.
