Creating really great cross-platform game experiences is complicated and challenging. Designers need to understand the differences between play on-the-go vs. sitting at home, account for input preferences across both mildly and radically dissimilar devices and find the way these devices communicate with servers and with each other. Product managers need to think of the cost of maintaining these connected experiences and discover effective ways to simplify that puzzle. Early technological choices determine what design pathways remain open and those design options may be critical to create a flawless compelling experience. Roei Livneh, Founder and CEO of Gingee, shares his experience developing cross-platform games and tools to help developers meet this challenge.
