For a long time macros have been in use by many players in all 3 age games, Age of Empires, Rise of Rome and Age of Kings. The users just didn't share with other players that they had the macro speed advantage.
A keyboard macro lets the user program hotkeys and mouse movements all under one key.
For example in a deathmatch game the user could click on one villager, type F1 and have 50 stable foundations,20 town centers, castle foundations,barracks foundations all placed on the map in less than a second.....all of this with ONE key. An entire military can be produced the same way. There are thousands of ways to configure macros for the aoe games.
In AoE deathmatches players are getting to pop 200 in less than 4 mins A bad bug is that many times units will be trained *in unbuild foundations* < Should macros be included in games so all players have a Level playing field? what do you think?
