"In battles, as verbal communication cannot be heard clearly, cymbals and drums are used as commands" As visual communication and eye contact are hampered, banners and flags are used as signals. Now the purpose of using cymbals, drums, flags and banners is to draw attention of the troops and focus them for combat under the direction of the commander. Once the troops are united as one body, the courageous ones will not advance forward by themselves and the cowardly ones will not retreat by themselves. This is the art of directing larges forces in battles. – Chapter Seven, Sun Tzu Art of War

In war good, communication with your troops, allies and even enemies his the key.

In most games MMO browser-based strategy game (like Three kingdom online, tribal war and travian) they have these feature built in.

If your a veteran player you can probably skips that part for other the advantage and disadvantage of each method will be explained.

In game feature

In game message

All these game have in game message, the quickest way to got a player whatever he his online or the next time he login.

It help you to find out if the user is still active, if he doesn’t answer after a few days or week you can presume he’s out.

The main advantage of this is that it’s quick and you’re almost sure the other player will read it next time he play.

The disadvantage is that entrusted player may read your message.

League message

Same thing has above but use by leadership and elite members of a league or tribes to send a message to the mass.

While it’s great to reach all your members, if there a spy in your league he might be able to read it and like normal message entrusted member can read it to.

Chat

Some of these game have in game chat, it’s great to talk directly to your peer, but you must be aware of the issues each room have.

From TKO chat here are the different room and how to use them.

World

Everybody on the server see it, so don’t tell sensitive info or information about what time it is or if it’s day or night, because other player might use this to attack you when your asleep or working.

League

Like the league message all your league member see this, beware of spy.

Private

Standard – One on one chat, note that you might be speaking to an entrust not the real player.

Internal forum

They work differently depending on the game, but like the league message, all league member see it (accept officer sub-forum). That some of them (like tribal war tribe forum) someone with an entrust can see it.

External to the game communication that might be useful.

External forum

The external forum solves most of the issues player with an entrust, only the player who registered can access it.

It can be useful to coordinate with ally too, an ally can have is own section of a forum and each tribes/leagues can share a section forum.

The main disadvantage is that you lose most of the feature of the in game forum, like writing the coordinate wills create a link directly to the in game location, this don’t work with an external forum.

IRC

You can always set up a IRC channel for you league. The advantage is that user can access it even if they’re not logged to the game and you can have control over who can be in the channel with a bot.

IM

Instant massaging can be useful specially the conference or group chat, you can talk to your buddy evens if they are not online (which can be annoying too if they are always poking you when the see you online).

Collaboration systems

like google wave, wiziq

I honestly haven’t planned anything with google wave but I did with wiziq and it really cool, you can have a draw  board and put the map on it and plan the attack and have a visual representation of the situation. It takes some effort to setup though but it might worth it.

Does any of you have use other method of communication to plan an attack or to plot something with your allies ?
