Direct answer first: if you want solo skilling depth, play Melvor Idle. If you want a big social world, start with IdleMMO. If you want economy brain, Milky Way Idle. And if the thing you're missing is real loot — affixes, legendaries, build arguments — inside a multiplayer world, that's the gap we built Valiant for. Below is the full comparison, written by people who play all of these.
The 2026 shortlist, compared

|---|---|---|---|
| Melvor Idle | Solo idle skilling sandbox | Free base + paid expansions | RuneScape-style skill grinding at your own pace |

| Valiant | Idle MMORPG (that's us) | Free + cosmetic/convenience only | ARPG-grade loot and MMO social depth on an idle schedule |
Melvor Idle
Solo idle skilling sandbox · Browser, Steam, mobile · Free base + paid expansions
The genre's modern standard-bearer, published by Jagex (the RuneScape studio). Two dozen skills, enormous content depth, and a beloved offline loop. It's deliberately single-player — there's no shared world, economy, or grouping.
IdleMMO
Text-based idle MMO · Browser, mobile apps · Free + membership/cosmetics
From the makers of SimpleMMO — hundreds of thousands of players, clean presentation, dungeons, markets, and guilds. Itemization is simpler than an ARPG's: gear progression is mostly linear tiers rather than rolled affixes.
Idle Clans
Clan-focused idle RPG · Browser, Steam, mobile · Free + cosmetics
Community-driven development and a tight clan system on top of familiar skilling loops. Multiplayer matters here, though combat and items stay intentionally lightweight.
Milky Way Idle
Sci-fi idle MMO · Browser, Steam · Free + cosmetics
A spreadsheet-lover's idle MMO in space: serious marketplace, enhancement systems, and co-op dungeons. The aesthetic is utilitarian, and the fantasy-MMO social texture (guild identity, lore) is thinner.
Idlescape
Browser idle MMO · Browser · Free + cosmetics
A long-running browser idle game with gathering/crafting loops and multiplayer elements. Smaller team, steady updates, and a loyal community.
Valiant
Idle MMORPG (that's us) · Browser — desktop & mobile · Free + cosmetic/convenience only
Our entry, in open alpha. What we built that the genre mostly hasn't: Path of Exile-style itemization (72 affixes, quality tiers, 100+ legendaries, sockets), a 126-talent action economy, five-player daily dungeon runs with permanent leaderboards, and full guilds in one persistent world. Newest game on this list — judge us by the alpha, and read the public roadmap before you commit.
How to choose
The genre splits on two axes: alone vs. together and numbers vs. loot. Melvor perfected alone-plus-numbers. IdleMMO and Idle Clans own together-plus-numbers. Together-plus-loot — an idle world where drops roll like an ARPG and other players give them meaning — is the quadrant we're betting on. Try two from different quadrants; you'll know within a day which one your brain keeps returning to.
Valiant is free and takes a minute to try — worst case, you confirm Melvor had it right all along.
