How much does the phone heat up for you guys while gaming?

How fast does it tend to heat up and how hot does it get? If you could compare to another phone that would also be useful, I'm still waiting proabably another day before I bite was hoping Verizon would get a different color also wanted to see if HTC ONE MAX is worth a damn or not but seems to be no real info on that phone yet.
