Mobile Multiplayer Open-World Roleplay Game

Multiplayer Open-World Mobile Roleplay Game

I am looking for an experienced game development team to build a high-quality multiplayer open-world roleplay game for iOS and Android.

The game should feel like a living online city where real players interact, choose careers/lifestyles, earn money, own vehicles/property, join factions, commit crimes, work legal jobs, and progress over time.

I am not looking for a template, reskin, basic simulator, or low-quality prototype. I want a strong foundation for a serious long-term online game.

Graphics / Visual Quality

Graphics are very important.

I want a modern realistic 3D style comparable to high-quality mobile open-world games, while still being optimized for smartphones.

Desired visual features:

* Detailed city environment
* Good lighting/shadows
* Day/night cycle
* Weather
* Quality character models
* Character customization
* Smooth animations
* Detailed vehicles
* Vehicle lights and basic damage
* Important building interiors
* Modern premium UI
* Adjustable Low / Medium / High / Ultra graphics

Performance and optimization on modern iOS and Android devices are extremely important.

Map / World

The first version does not need a huge map. I prefer a smaller, detailed and active city instead of a massive empty world.

Potential locations:

* Downtown
* Residential areas
* Luxury district
* Industrial area
* Police station
* Hospital
* Government buildings
* Vehicle dealerships
* Garages
* Fuel stations
* Banks
* Shops

* Highways
* Airport area
* Countryside/desert areas

The map, assets and identity must be original or properly licensed.

Multiplayer

Multiplayer is the core of the game.

Players must be able to interact with other real players in a persistent world.

Required architecture should support future scaling.

Features:

* Player synchronization
* Vehicle synchronization
* Interaction synchronization
* Text chat
* Proximity voice chat or recommended voice solution
* Private/faction chat
* Player IDs/names

* Persistent accounts

Important gameplay systems should be server-authoritative wherever possible.

Accounts / Persistence

Player progress must be stored permanently.

Stored data should include:

* Cash/bank balance
* Character
* Clothing
* Vehicles
* Inventory
* Jobs
* Faction/rank
* Property

* Businesses
* Progression

The backend/database must be secure and scalable.

* Buy/sell vehicles
* Ownership
* Garage
* Keys
* Lock/unlock
* Fuel/refueling
* Damage/repair

Driving should feel enjoyable and reasonably realistic.

Economy

Persistent economy including:

* Cash
* Bank
* Player payments
* Salaries
* Purchases
* Fines

* Business income
* Criminal income

Prices and economy settings should be adjustable server-side without requiring a full game update.

Jobs

Legal jobs may include:

* Taxi

* Trucking
* Bus driver
* Mechanic
* Tow truck
* Courier
* Garbage collection
* Construction
* Fishing/mining

I would also like an in-game phone with possible features:

* Speed hacks
* Teleport hacks
* Money modification
* Inventory duplication
* Fake purchases
* Damage modification
* Unauthorized items/vehicles
* Client manipulation

Money, inventory, ownership and important gameplay logic should not trust the client.

Monetization

The architecture should allow future monetization such as:

* Premium membership
* Cosmetic clothing
* Vehicle cosmetics
* Character customization
* Battle pass
* Animations
* Extra character slots
* Cosmetic property items

I do not want extreme pay-to-win gameplay.

Technology

* Expected server capacity

I am looking for a serious development team interested in a long-term online multiplayer project, not someone simply combining marketplace assets into a quick prototype.
