Thanks for using Apple Support Communities.
To start with, it is normal for an iOS device to get warm under heavy use, especially when playing a graphis-intensive game, as the device itself acts as a heat sync. If you'd like to learn more about keeping your iPhone within the acceptable temperature range, take a look at the article below.
