Pokémon Trading Card Game Online

Metal War Online: Retribution is an action-racing MMO released in 2015. The game had niche appeal with vehicle combat, and over the years its popularity has declined sharply due to lack of major updates and competition from larger titles in the genre. Current player engagement is likely very low, with only a small, dedicated fanbase remaining.

Pokémon Trading Card Game Online was a popular digital adaptation of the Pokémon TCG, released in 2011. The game maintained a modest but dedicated player base due to the Pokémon brand, but its daily active player count declined after the launch of Pokémon TCG Live (which replaced PTCGO starting in 2023). The original client is no longer actively supported, and most of the active player base has transitioned to Live. Estimated daily players on the old service are very low, possibly only a few thousand globally, but the Pokémon TCG franchise remains strong overall.
