EB Online was created in May 2010 in order to facilitate multiplayer gaming for the EB community. Before EB Online, people connected in myriad ways. Some users would connect via Gamespy, while others would use VPN network software such as Hamachi, Leaf and Tunngle, among others. The most reliable of all these methods proved to be the zero-configuration VPN software Hamachi. This realization followed an era of proliferating networks dedicated to EB multiplayer gameplay. The user V.T. Marvin compiled a list of several of these Hamachi networks on EB's forums at the Guild. Over time, these networks became filled with offline members who had failed to leave the Hamachi networks. Hamachi networks, each having a limit of 16 members at any one time, were causing a problem for the community now, who wanted eagerly to battle online. It was clear that a regularly administered system was necessary to maintain online gameplay for longer periods of time. The user vartan, who also started this wiki, created EB Online, a system of Hamachi networks that would constantly be purged of people who forgot to leave the networks when signing off from Hamachi.
EB Online started as any other Hamachi network but soon had a website of its own, with rules and a complete system of adjudication and guidelines for tournaments that are now held every month. Rules include everything from factional unit lists, to fair play rules, to army compositions and more. These tournaments are self-sufficient save for the network purges and the tournament threads on the Guild, one for each monthly tournament. The first tournament held was the special edition EB Online July 2010 Tournament, an anniversary homage to the successful multiplayer tournament driven by Guild users Phalanx300 and Antisocialmunky in July 2009.
