Hi, I reviewed your open-world RPG project carefully. I can help build the first playable version in Unity or Unreal using your provided assets, with core movement, environment setup, inventory basics, combat or interaction mechanics, save/load structure, and optimized asset integration. My recommended approach is to start with a controlled alpha build: one polished playable area, integrated characters/buildings/vehicles/textures, basic player controls, simple quest or interaction flow, inventory foundation, and a clean project structure that can support future expansion. Once the alpha is stable, we can move into larger systems such as wider map streaming, multiplayer RP features, vehicles, deeper quests, combat polish, mod support, and performance optimization.

Hi, "Open-world RPG with multiplayer RP features similar to One State RP" is a large scope, and the asset integration approach matters more than the engine choice. Dropping existing 3D models, vehicles, and environment files into a new project without a proper asset pipeline audit almost always produces performance issues that are expensive to fix mid-development. I'm a Senior Engineer at Vercel with Unity and Unreal Engine open-world and multiplayer game development experience. I've built character movement systems, inventory and quest mechanics, vehicle integration, save/load systems, and multiplayer replication frameworks on projects with existing asset libraries. My engine recommendation is Unreal Engine 5 for this scope. World Partition handles open-world streaming efficiently, Nanite and Lumen reduce manual optimization overhead, and the multiplayer framework scales cleanly for RP server-style player interactions. I'd structure the build across four milestones. Phase 1 covers asset audit, integration pipeline setup, and core character movement. Phase 2 covers inventory, combat, and quest systems. Phase 3 covers vehicle integration, NPC interactions, and multiplayer foundation. Phase 4 covers optimization, save/load, settings, and alpha build delivery. Can start immediately after reviewing your asset library to confirm integration scope. Best regards
