Pokémon Donjon Mystère Online

VS

Realm of the Mad God

Pokémon Donjon Mystère Online is a fan-made, French-language online adaptation of the Pokémon Mystery Dungeon series, run by an independent team (Team_PDMO). While it offers multiplayer and seems to have a persistent world, such fan games typically attract a small, dedicated audience. There is no indication of mainstream popularity or large influxes from official Pokémon channels, so daily active players are likely in the low hundreds.

Realm of the Mad God is a browser-based, free-to-play MMO bullet hell shooter first released in 2011. While its peak passed years ago, it still maintains a niche but active player base thanks to frequent updates from DECA Games and its unique gameplay loop. As an indie MMO, it is unlikely to have more than 10,000 daily active players but retains a dedicated community.
