Requiem: Memento Mori is an older horror MMORPG developed by Gravity Interactive, known for darker themes and mature content. The game launched in the late 2000s and has maintained a small, dedicated player base, but is now quite niche with very limited daily activity typical for legacy free-to-play MMORPGs outside major publishers. Based on genre, age, and publisher reputation, current daily players are likely in the low hundreds.
