Why is my iPhone 8 getting warm?

[EdgeyTheHedgey]

Hello. I recently got an iPhone 8, and have found that it get’s quite warm when I play games. I installed sonic 4 on it, and found that almost immediately after I start playing, the phone begins to become warmer on the back. This problem only occurs when I play games (sonic 4, infinity blade etc.), and though I normally stop before it can get too hot, I’m not sure if This is normal or not, so any guidance on this issue would be helpful.
