FlatMMO
A free 2D browser MMO heavily inspired by Old School RuneScape — skills, grinds, PvM and raids.

A free, 2D browser MMO that lovingly cribs from Old School RuneScape: skills to train, grinds to chase, PvM, raids, and plenty of AFK activities for the idle dopamine loop. Developed in the open by a solo dev who regularly posts updates on r/incremental_games — community-driven and rapidly expanding.
