Idle, but not alone
Most idle games are single-player. In IdleWorlds the items you craft are sold to other players, the world boss is fought by everyone online at once, and guilds clear raid bosses together.
You choose what your character does, it keeps doing it, and you check in when you like: a few minutes on your phone or an evening of planning gear and trades.
What you get in IdleWorlds
10 skills: Combat, Mining, Smithing, Herbing, Alchemy, Jewelcrafting, Spellcrafting, Tailoring, Woodcutting and Construction. Each one feeds the others, so a sword starts as ore you mined yourself.
34 zones to fight through, world bosses the whole server hits together, and 5 raid bosses for guild groups of up to 8.
A player-run market with listings and buy orders, guilds of up to 20 players, live chat, leaderboards, and a solo self-found (SSF) league if you'd rather do everything yourself.
Your character keeps working while you're away, so you come back to finished crafts, levels and loot.
