One RP is a gaming project that offers a feature-rich roleplay experience for Grand Theft Auto V, combining roleplay with progression systems associated with MMORPGs. Players create characters and build their own stories in Los Santos, choosing paths that range from legitimate work and business to street racing and crime. The world includes more than 150 vehicles with distinct handling, sounds, tuning, wear, and accident systems. Its player-driven economy connects resource gathering, processing, crafting, production, and trading through more than 1,000 recipes.

Players can develop skills and professions, take part in PvE and PvP activities, join factions, and explore systems for property, combat, and criminal enterprise. Activities include fishing, hunting, mining, diving, and team operations, while factions such as police, EMS, gangs, and the army have dedicated tasks and management features. One RP provides account registration, a game launcher, a knowledge base, FAQs, news, and community channels including Discord, Telegram, and YouTube. Players need an original copy of GTA V to get started.
