IdleOn is an incremental MMO from solo developer LavaFlame2: a 2D RPG where your heroes keep fighting and gathering while you are offline. It entered Steam Early Access in April 2021, reached full release in November 2025, and runs on PC, in the browser and on phones.
Your account is a team of up to eleven characters of different classes, each with its own job. Beyond combat there are many non-combat skills, from cooking and woodcutting to alchemy, construction, farming and sailing. Progress is all about upgrades: you log in, spend what piled up while you were away, tune skill trees and push your stats.
It suits idle-game fans happy to check in briefly for years. There is less real multiplayer than in a typical MMO. All content is free; the shop sells boosts and pets. No Russian language.
