Three.js Browser-based 3D Game Development plus video tutorial

I need an experienced Three.js/JavaScript game developer to create two complete browser-based 3D games:

1 FPS Game – first-person combat, enemies, weapons, missions, levels, UI/HUD and required gameplay systems.
1 Simple Strategy Game – map-based strategy gameplay with units, buildings, resources, objectives, enemy AI and turn/game management.

For each game, a complete game-development tutorial video must also be created, explaining the actual development process step-by-step, including setup, coding, assets, gameplay mechanics, UI, testing and final implementation.

I will provide the game concepts, detailed specifications, references and required assets/details.

Deliverables
Fully playable and polished Three.js games
Complete source code and project files
All required assets/integration
Complete development/tutorial video for each game
Testing, bug fixing and optimization
Final deployment-ready versions

Full commercial rights and IP ownership of the custom work will be transferred to me upon final payment. The freelancer must disclose any third-party assets/libraries and ensure they have appropriate commercial licenses.

Please provide relevant Three.js/3D game development examples, estimated timeline and total cost.
