ijji was a free multiplayer game portal website. Games hosted at ijji ranged from traditional shooters and MMORPGs to more accessible casual games, all of which were free to download and play, and with the majority featuring competitive multiplayer gameplay. The ijji website opened on July 7, 2006. The American-based game portal has published some well-known worldwide titles that include Alliance of Valiant Arms, GunZ, and Soldier Front.
ijji decided to focus more on the "hardcore" gaming segment, as they had already released Alliance of Valiant Arms and Soul of the Ultimate Nation in 2009. ijji later released Genesis A.D into open beta.
ijji surpassed 10 million unique registered users in November 2009 and created a new logo for their game portal. The old orange ijji logo was replaced by a new metallic looking logo. In this same month, all flash games on ijji.com that required no download were closed and removed from the game portal.
In June 2011, ijji partnered up with Steam, the popular game distributing platform developed by Valve Corporation, and released Alliance of Valiant Arms as one of the free-to-play games available on Steam. This partnership allowed for the increasing of the community size of the free-to-play game portal. As a celebration, ijji gave away a free exclusive weapon, the British L8A52 rifle for new users who signed up on Steam.
Starting on October 26, 2011, ijji removed the ability to sign up for a new ijji account. Instead, users will log in with their Facebook account to play ijji games. Existing users are still able to log in with their old accounts.
