I am looking for a GameMaker developer to build a simple management game framework that can be reused for multiple themes. The goal is NOT to create a complete game, but a generic framework that I can later customize myself into different games such as: Horse management and breeding Football management Basketball management Other sports or management themes Required Features Main menu Player profile Currency system Generic entity system Statistics system Match/competition simulation system Save and load system Data stored in JSON files where possible Clean and organized code Important The framework must NOT be hardcoded for horses, football, or any specific theme. For example: Entities should be configurable. Stats should be configurable. Competitions should be configurable. Names and descriptions should be loaded from data files. I want to be able to replace content and create a different management game without rewriting large parts of the code. Not Required Multiplayer Online accounts Cloud saves In-app purchases Advertisements Advanced graphics Animations Fancy UI Simple placeholder graphics and menus are completely acceptable. Deliverables Full GameMaker project files Well-organized code Basic documentation explaining how to add new entities, stats, and competitions Please Include Your GameMaker experience Examples of previous projects Estimated completion time This project is intended as a foundation for future management games, so code quality and flexibility are more important than graphics.

Hi I can build a reusable GameMaker management game framework with clean GML code, JSON-driven data, placeholder UI, save/load, currency, profiles, entities, stats, and competition simulation. The main technical challenge is avoiding hardcoded theme logic so the same framework can support horses, football, basketball, or other management concepts without rewriting the core systems. My approach would be to create a data-driven architecture where entities, stats, names, descriptions, competition rules, rewards, and progression values are loaded from JSON configuration files. I would structure the project with modular GameMaker scripts, controllers, UI screens, data loaders, validation helpers, and documented extension points. The simulation layer can use configurable formulas for match results, rankings, entity performance, random events, and stat-based outcomes. Save/load would store player profile, currency, owned entities, competition progress, and generated state in organized JSON files. This gives you a flexible foundation that prioritizes maintainability, customization, and future theme expansion over unnecessary graphics or hardcoded gameplay. Thanks, Hercules

★•══•★ Hi client ★•══•★ I have experience building modular game systems, reusable gameplay frameworks, JSON-driven data structures, and clean project architectures that can be extended into multiple game themes. My approach will be: ✔️ First, I will design a generic GameMaker framework with configurable entities, stats, competitions, currency, player profiles, and save/load structure. ✔️ Then, I will build the core systems using JSON files wherever possible, so names, descriptions, stats, and competition rules can be changed without rewriting the code. ✔️ Finally, I will provide the full GameMaker project files with organized scripts, placeholder UI, and documentation explaining how to add new entities, stats, and competitions. I understand the key goal is flexibility, not fancy graphics, so I will avoid hardcoding the framework for horses, football, basketball, or any single theme. One key question: Which GameMaker version are you currently using, or should I build it in the latest stable GameMaker version? Best regards. Rico

Hi, most management game frameworks fail when logic is hardcoded into a single theme, making reuse across different sports or systems extremely limited. The requirement for fully configurable entities, stats, competitions, and JSON-driven data points points to a data-architecture problem, similar to systems built around separating logic from inputs so they stay flexible and scalable. I would design a reusable engine structure where all entities, stats, and competition rules are driven through external JSON configs, with a core simulation layer handling progression, economy, and match outcomes plus a clean save/load system. What level of match simulation do you want, purely statistical resolution or something more event-driven that can be expanded later? Best Regards, Fizza Nadeem K

I looked at your GameMaker management game framework requirements and see you need a reusable, non-hardcoded system with configurable entities, stats, competitions, and JSON data storage, plus main menu, player profile, currency, match simulation, and save/load functionality. GameMaker's built-in `json_stringify` and `json_parse` functions make JSON data storage straightforward , and an entity-component system pattern would allow flexible configuration for different themes like horse or football management . The deliverables include a full GameMaker project with well-organized code, JSON-based data loading for entities and competitions, a generic simulation system, save/load functionality, and documentation explaining how to add new content without rewriting code. The project will be completed in 5 work days at a total cost of 500 EUR. Do you have specific entity attributes and competition rules in mind that should be configurable? Should the save system support multiple save slots or just a single auto-save? Let me know your answers. I can start right away.

Hi, Would you like the framework to support adding entirely new management systems through JSON configuration alone, or is some scripting for custom mechanics acceptable? I have experience with GameMaker development, can share relevant project examples, and estimate this framework can be completed within about 3 to 4 weeks. I understand you're looking for a reusable GameMaker management game framework that is data-driven, modular, and easy to adapt to different themes without rewriting core systems. I have extensive experience designing scalable software architectures and game-related systems with a strong focus on clean, maintainable code, reusable components, JSON-based data management, and flexible frameworks that can be extended for future projects. My approach would be to build a generic core with configurable entities, statistics, competitions, currency, save/load functionality, and simulation logic while keeping all theme-specific content in external JSON files. This will allow you to create new management games by modifying data instead of changing the underlying code, and I'll provide clear documentation explaining how to add new entities, stats, and competitions. I'd be happy to discuss your vision in more detail via chat and answer any questions before we get started. Looking forward to hearing from you!

⭐ Hi there ! Let's set meeting schedule for ur project more detail . This framework idea makes sense to build in GameMaker as a clean reusable base not as one fixed game Core part will be data driven GML with JSON configs for entities stats competitions names descriptions and starting values So later u can switch horse mgmt to football or basketball by changing data files instead of touching half the code GameMaker side can include main menu player profile currency generic entity manager stat manager competition sim save load and simple placeholder UI Code will be organized in small scripts and controllers so each system stays separate No fancy graphics needed here and honestly that is good for this type of project The important thing is making the structure clean first For prev work samples can share small prototype or gameplay system examples and explain the architecture before start Question from my side Do u want this built for desktop first or mobile export also needed from the first version Timeline : 18 days Total Budget : 550 EUR
