After decades of annual releases, what was so different that making Football Manager 2025 resulted in such a disaster? Well, with developer Sports Interactive moving from its own technology to Unity, developers believe the team underestimated the mountain of work needed to adapt such a bespoke series to new tools.Football Manager 2025 devs may have underestimated their workIn a piece by The Athletic, former communications director on Football Manager, Ciaran Brennan explained that the series had been built on the same technology since 2004.

Porting from a custom engine to Unity will have its challenges. There is no magic button that converts all your code, libraries and art. There are different rules, file formats and ratios. Often, that mountain of work is underestimated.However, the developer explained that the shift to the engine will provide many advantages as Sports Interactive no longer needs to develop and update its own internal tools. Many developers have made this shift as of late with Cyberpunk developer CD Projekt moving to Unreal Engine as well as Halo Studios.For many Football Manager fans, its a shame that there wont be a new entry this year, but its also a good sign. FM26 should be more polished, and the future of the franchise is secured. This situation should also give players some insight: game development is hard, and its never as easy as just switching engines.
