Write one game that runs on PC, PlayStation, Xbox, Switch, and mobile -- without losing your mind rewriting everything five times.
Cross-platform development is the practice of building a game that runs on multiple platforms from a shared codebase. Modern game engines like Unity and Unreal abstract most platform differences behind common APIs, but the reality is messier than the marketing suggests. Each platform has different GPU capabilities, memory constraints, input methods, certification requirements, and performance targets. A game targeting both Switch and PC needs to handle wildly different hardware specs. Controllers, keyboard-and-mouse, and touchscreen all need distinct UI and control schemes. Platform-specific features -- Xbox achievements, PlayStation trophies, Steam Workshop, Nintendo's sharing features -- require platform-specific integration code. The abstraction layer handles maybe 80% of the work; the remaining 20% platform-specific code is where most of the pain lives.
Example
Hades shipped on PC, Switch, PlayStation, and Xbox, each with platform-specific optimizations and UI adjustments. Supergiant Games built the game primarily in their custom engine but had to create specific rendering paths for Switch's weaker hardware and adapt the UI for each platform's controller conventions -- work that goes unnoticed when done well but is immediately apparent when done poorly.
Why it matters
The financial case for cross-platform is overwhelming -- each additional platform multiplies your potential audience. But the technical and logistical cost of supporting multiple platforms is real. The developers and engines that do it well gain access to the broadest possible market while maintaining quality across every device.
