A private league in POE 1 is a sandboxed version of the game where you can only interact with players who are in the same private league. The means a fresh game economy, every players starts a new character from scratch. This private league was launch a little over 2 hours ago by Pohx, a youtuber who is known for making videos for new players.
Almost 20,000 players have registered so far. This is a pretty substantial number for a private league.
With Jonathan announcing that POE 1 development has been indefinitely delayed, this may be your last time to experience Path of Exile with other active players and fresh economy. The game is free to play.
If you don't know what to build to play, go to youtube and search "poe 3.25 lightning strike", "poe 3.25 righteous fire", "poe 3.25 archmage ice nova", "poe 3.25 hexblast mines", "poe 3.25 power siphon mines", "poe 3.25 holy relic", or "poe 3.25 bama". It is important that the video says 3.25 because builds from previous patches will not work.

In case you were wondering, BAMA stands for Blink Arrow, Mirror Arrow. It's a minion build where you summon a bunch of clones of yourself that shoot your bow.
