No matter how the game is, how good it looks, or how well it is designed, if the game does not run on the target platform, then it cannot be successful. We already know that Android has various sets of hardware configurations.
The main variations of hardware are specific to the processor and memory. In the case of processors, it depends on their speed and quality. In case of memory or RAM, it is only the volume.
Even today, RAM can vary from 512 MB to 4 GB in Android devices. Memory optimization should always have a minimum target of RAM as per design. So, memory optimization is immensely important in order to run a game on the minimum available RAM.
Sometimes, the developer fits the peak usage within the target limit of memory. However, they perform on a testing device, which does not project a real-time scenario most of the time. There is always an error margin. So, it is not always true that if the game runs on a certain limit of RAM, it will always be provided...
