If u search on here youll see a few threads. It seems the only thing in common here is the silver color model does this more often and the dark grey colored model does this less. Relevance, Idk but just the common theme. I would say for sure hands down get a new replacement!
I don't play those games but do play dead trigger 2 often on highest graphic settings. This game by far has to be one of the most graphic intense mobile games for a gpu imo at least. I can play 20min straight and using the GSam battery app after playing the highest I've seen the temp get is 98 degrees F. That is nothing for a device like this. My last device was over clocked tegra 3 chip on the HTC one X+ and 10min of same game phone got to around 115-120 degrees F, now that is Hot!
Since everyone has an opinion on the word "Hot" I would suggest getting GSam battery app for free. Gives u the exact temp of ur phone to help compare. I also have a case on my device so in theory my phone should get even hotter, less ventilation.

Hottest I ever got this device so far is 101 degrees F. I did this on purpose too to see what it takes since this thing does not get hot. Had to play YouTube videos, download mp3 files, play dead trigger 2, download emails, be on Facebook, all literally at the same time and running in the background multi tasking between them all. Now this is a hell of a phone!
