Overcoming File Size Limits: Bringing a 30GB Train Simulator Game to High-End Mobile Tablets

Allow me to introduce myself—I’m a developer specializing in PC and console platforms, currently working on a Train Simulator for desktop and console systems. While I’m eager to extend the complete gaming experience to mobile devices, I’ve encountered a challenge. The game, boasting numerous highly detailed open worlds, exceeds 30GB when compiled for Windows/Mac.

To my delight, I’ve managed to run it on my iPad M1 with some adjustments in the editor. However, a significant obstacle arises when attempting to publish it on Apple platforms, given their 4GB file size limit. I’m particularly interested in releasing the game on high-end mobile tablets. Is there a viable solution or workaround for this limitation? I’m open to any advice or suggestions to navigate this constraint.
