The read
The real split is the shape of the climb. SimpleMMO has one character level, and clearing level n costs 50 × n XP — level 345 needs 17,250 — with no ceiling in sight: v12.87 added level-up announcements at 1,000,000+. IdleMMO's public skill index lists 10 skills, each with its own cap: Combat 100, Dungeoneering 95, most gathering skills 90, Alchemy 50. SimpleMMO is a number that keeps going up; IdleMMO is a set of skills you can finish one at a time.
They also ask for your time differently. SimpleMMO's main loop is a travel button: each press is a step that can turn up gold, XP, an item or a fight, so it suits short, frequent check-ins. IdleMMO runs an action on its own and keeps going while the tab sits in the background. Both run in a browser and on iOS and Android, so neither needs a particular device.
Combat is more open in SimpleMMO, at least on paper. The community wiki documents the formula — max hit is Strength minus 9/11 of the target's Defence, hit chance is 3.5 × Dexterity ÷ Defence — and that is what our SimpleMMO combat calculator runs. IdleMMO publishes the content instead: 47 enemies, 18 dungeons and 11 world bosses on timed windows. Both games build their group play around world bosses; SimpleMMO spawns 12 plus 1 god boss every Monday.
The markets differ in what each charges and shows. SimpleMMO's player market takes 3.5% once an item sells, 2.5% more if you buy with bank gold, and keys and Diamond Shards cannot be listed. IdleMMO publishes a daily average price per item plus a companion exchange listing 15 pets for gold. Guilds exist in both; SimpleMMO's level up to 100 and cost 15,000,000 gold to found. On this site IdleMMO has the full set, 11 calculators with boss timers and databases, while SimpleMMO has a combat calculator, an XP calculator and written guides.
