I have the full concept for a PC-only 2D MMO sandbox inspired by Pixel Worlds and I’m ready to see it running. What I need right now is the playable foundation: account creation that stores credentials securely, a clean main menu that leads into the world, and enough networked infrastructure so I can begin plugging in the building, chat, trading, and character-customization systems I’ve already designed. As Of Right Now I just need the basics (Main Menu, Account creation and world making/saving if possible) Engine choice is open—Unity, Godot, or anything you’re comfortable with—as long as the end result is stable, well-commented, and easy for me to expand. A lightweight server back end (Node, .NET, or similar) plus a simple database for user data will be expected. Deliverables • Login/registration flow with encrypted password storage • Main menu UI that routes to create account, log in, settings, quit • Basic multiplayer lobby/world scene proving persistent connections for multiple players • Clear, modular code structure and brief setup/readme so I can continue development Acceptance criteria — A compiled PC build and full project source that launches to the main menu, registers and logs in users, and drops them into the shared 2D scene without errors. — Documentation outlining project architecture, server setup, and where future systems (building, chat, trade) will hook in. Let’s set up a quick milestone for the menu and account flow; once that is solid, we can iterate on additional features.

Hi, good day. I understand you need a foundational PC-only 2D MMO sandbox prototype with secure login/registration, a clean main menu flow, and a basic persistent multiplayer world that can later support systems like building, chat, trading, and customization. The core technical challenge here is setting up a stable client-server architecture with encrypted authentication, session handling, and a lightweight real-time networking layer for multiple players in a shared scene. My approach would be to build this in Unity or Godot with a modular client, implement a Node/.NET backend with secure password hashing and token-based auth, and create a simple multiplayer lobby that transitions authenticated users into a shared world instance with persistent connections. Everything would be structured so future systems can plug into the networking and data layers without refactoring.

Your vision for a 2D MMO sandbox, reminiscent of Pixel Worlds' core loop, is precisely the kind of foundational build I excel at. I've previously architected similar networked game states, focusing on robust user authentication and seamless transitions to persistent game worlds, ensuring a secure and scalable starting point for your ambitious project. My technical approach will leverage a C#/.NET backend for secure account management and player data persistence, likely utilizing PostgreSQL for its reliability and scalability. For the client, I'm proficient in both Unity and Godot. Given your PC-only requirement, Unity offers a mature networking solution (UNet or Mirror) that's well-suited for rapid prototyping and future expansion. The core will include a secure account creation flow, a functional main menu with scene loading, and a basic networked world instance capable of saving/loading player positions and essential world state. To ensure we're perfectly aligned, could you clarify your preferred approach to client-server authority for core gameplay elements like player movement and world interaction? Additionally, what are your initial thoughts on the data structure for world saving to accommodate future complex builds? I'm eager to discuss these details and how we can quickly bring your 2D MMO sandbox to life.

Hi, I can build the playable foundation for your PC-only 2D MMO sandbox. For the first milestone, I would focus on the core flow: ✓ Main menu UI ✓ Account registration/login ✓ Secure password storage ✓ Basic shared 2D world/lobby ✓ Simple backend + database ✓ Clean project structure and setup notes I have experience with Unity, C#, Node.js, backend systems, and multiplayer-style game architecture. I can keep the code modular so future systems like building, chat, trading, and character customization can be added later without rewriting the base. One quick question: do you prefer Unity + Node.js backend, or should I choose the simplest stable stack for this first version? Regards, Sergio

The bid amount and timeline shown are rough starting points, we will firm up the real numbers once we walk through the full scope together. What you're describing is the skeleton of a 2D MMO sandbox, the kind of foundation that everything else plugs into later. You need the account system wired up securely, a clean main menu that routes correctly, and a live multiplayer scene where multiple players can actually coexist before you start layering in building, chat, and trading. Getting that base solid now means none of those future systems will fight each other. Here's how we'd approach this: - Engine and project setup: Unity with C# is our pick here. It handles 2D multiplayer well, the scene structure maps cleanly to an MMO architecture, and your future systems (building, chat, trade) have natural hook-in points from day one. - Account flow: Login and registration backed by a lightweight Node.js server, passwords hashed with bcrypt, user records stored in a simple MySQL or SQLite DB. Nothing fancy, just solid and safe. - Main menu UI: Clean scene in Unity, buttons routing to Create Account, Login, Settings, and Quit. No clutter, easy to reskin later. - Multiplayer world scene: Mirror or Unity Netcode for GameObjects to handle persistent connections. We'll get multiple clients dropping into the same 2D scene and staying there without desyncing or dropping. - Code structure and docs: Modular folders, commented code, and a short README covering the server setup and where each future system slots in. After a short scope chat we'll put together a written proposal covering deliverables, timeline and a firm price. Want to jump on a quick call this week to walk through it? Best, 96 Studio

Hello! I've built 2D MMO foundations with account creation, persistent worlds, and basic multiplayer. I use Unity, C#, and Node.js daily. Example: a sandbox game needed secure login and a shared world scene; I set up encrypted passwords, a main menu, and a lobby where multiple players could connect without errors. For your project, I'll deliver registration, main menu, and a basic networked world scene with clean, modular code. I can have the playable build ready in 52days. Ready to start on the account flow first? Thanks!

Hello. I can help you build a solid, lightweight, and scalable infrastructure for your 2D MMO. Based on your project requirements, I propose to take care of the most critical part for your initial milestone: the complete backend server and the database setup. Building a robust backend from day one is vital so you can later integrate chat, trading, and character persistence without any performance bottlenecks. What I will deliver for $50 USD: Lightweight Backend Server: Developed in Node.js (Express), which is ideal for MMO games due to its highly efficient handling of concurrent connections. Secure Account System: Complete registration and login flow with securely encrypted password hashing. Optimized Database: A clean structure ready to store user credentials, fully prepared to scale up with future tables for character data, inventories, and worlds. Clear Documentation: Well-commented code and an architecture guide showing you exactly how to connect this server to your game client (whether you choose Unity or Godot). I have solid experience working with production environments, secure environment variables (.env), and server optimization, ensuring your setup runs smoothly without port conflicts or connection drops. How about we set up this database and server infrastructure today so your game engine has a rock-solid core ready to connect? I am available to start right now.
