Quick recap of this article
The commercial success of a game hinges on many factors, not least of which is whether users have a good reason to buy/download it. Another factor with just as much importance is reach – how many platforms and devices you can make the title available to. If you want your bases covered in this regard, you would surely benefit from learning how to make a cross-platform game. This is exactly what we will help you with in this article.
What games are cross-platform?
Cross-platform games are made through full-cycle development, where the application is built for several platforms at once, and available on multiple platforms at release. For example, you are not making the game for PC and later porting it to mobile, but rather making several versions simultaneously.
The benefit of cross-platform development over porting lies in time (and its relative equivalent – money). Though it normally takes longer to make a cross-platform game than a native one for a single platform, this is still much faster than making one game version and remaking it later through porting.
This is a trap that many games have fallen into (Fall Guys, Among Us, Fortnite, to name a few): the developer placed their bet on 1 or 2 platforms, but after their game blew up in popularity, they had to go through a painful and lengthy process of adapting it to new platforms.
The key thing to understand about game development is that though you are making several game versions at once, you don’t have to divert much attention or many people to these different directions – it is mostly a single stream. Thanks to game engines and other helpful cross-platform tools, the unified code for a game can be transpiled into different languages and packaged into apps for the corresponding platforms.
The first stage of game dev mostly consists of planning and laying the foundation for the project. Everything usually starts with an idea or vision, which is translated into concept art, preliminary designs, and notes about how it can be implemented. When the feasibility and requirements of the project have been defined, they are usually added to a game design document (GDD), which serves as an important reference for the project moving forward. It is also common for a company to create a prototype in this stage to make sure that the key planned functionality can be utilized.
This is when the magic happens. It also happens to be the lengthiest and hardest stretch of the project. With the pre-production materials and results in hand, developers get to work creating the game, while artists get to work creating the assets for it. Production usually takes months, and can easily take years for large or understaffed projects.
Though the game logic and mechanics usually stay the same from platform to platform, the specialists working on the project also contemplate platform-specific things, like how to fit UI and game elements on smaller/larger screens, how to optimize performance, and whether to cut/add certain features. This leads to partial branching of work as they delegate some time to code and content meant for individual platforms.
3. Testing and release
Though QA game testing begins in the production stage as new bits and pieces of the game are created, it really ramps up as the game nears completion. QA engineers thoroughly check the game for bugs or issues that might impact the user experience, offering suggestions. They also test the software on different platforms, since some code and scripts may not carry over well. With the game polished, it can get a partial or full release. A partial release (known as a beta) is meant to give a limited number of players a taste and make some final changes based on their feedback.
Nowadays, it is extremely common for companies that make games to stay involved in their maintenance for years to come. First, this can involve maintaining online services (like matchmaking). Additionally, it will usually involve periodic patches, updates, and fixes that improve the user experience. Some game-making companies even choose to keep their players engaged by adding new content to the application over time, through DLCs, season passes, etc.
Looking for professionals to cover this pipeline?
As you get started with your project, we suggest keeping the following tips and suggestions in mind which can help make the process smoother and more painless.
Implement social features for better reach
If your game already has multiplayer features, you can make it easier for people to enjoy it with their friends by enabling cross-play. In other cases, you can at least add some social features that will let users compare their results/scores.
Don’t hesitate to develop internal tools
Your developers will likely encounter some bottlenecks or problems that force them to repeatedly deal with certain tasks. In these situations, it is sometimes faster to build an internal tool that automatically completes the task than to do it manually every time.
Choose the microservices approach
This is just our own two cents on the microservices vs monolith debate. We have found it much easier to modify particular modules (microservices) for multiple platforms than changing the whole architecture to fix a small problem. Hopefully, you will have the same positive experience with this approach.
Reuse components where possible
From 3D assets to game code and UI elements, there are many parts of the game that you can reuse, saving plenty of time and effort. The same principle applies to parts bought or downloaded online – using ready code/scripts/assets can really help you speed up development.
We all know that software development is no walk in the park, and many of your game developers are probably already familiar with the main difficulties in their line of work. But what about the challenges specific to cross-platform development? Let’s take a look:
As a studio that has developed hundreds of cross-platform projects over the years, we want to draw your attention to tech stack choices. They will have a huge impact on the flow and complexity of your development process.

We shouldn’t have to tell you this, but game development is expensive. Even the cost of developing a mobile game can reach hundreds of thousands of dollars. As for developing for multiple platforms, it does take a little more time and is thus even more costly.
So, what can you do about cutting costs?
One of the most effective solutions available nowadays is to find a reliable outsourcing partner that will give you a good rate. Most outsourcing companies operate in countries with a low cost of labor, so you often end up paying less than you would for specialists hired locally.
This is certainly true with Game-Ace.
Our studio is based in Ukraine and offers very advantageous terms of cooperation, as well as a large team of specialists with solid experience in game dev. This experience certainly extends to cross-platform titles, which we build just about every month. If you have a project in mind that you want to get off the ground, just send us a message. We will be happy to discuss it with you!
