Why shouldn’t IOS and Android be a priority ?
In 2015 Clash of Clans was the second biggest selling game across all platforms with $1,345,000 sales , only beaten by League of legends on PC $1,628,00 . So the second biggest selling game of 2015 was on Mobile ! If one platform NEEDS networking support it’s mobile, where the vast majority of peoples social apps are.
I get that the OSS for Steam was a must, seeing as it’s the platform that every UE4 dev has access to. But why stop there ?
