I have a 2013 Macbook Air 1.7 i7 and I am playing SimCity on it. But for some reason every time I play the fans go nuts and the computer heats up. I know this can be normal since the Macbook is using a lot of resources. But is it ok to play the game for a couple hours with all the heat and fans?

or can this do more harm than good?

You're fine. All Intel based Macs have a built in overheat protection circuit...if it hits the redline it will just shut down...playing intensive games and high fan speeds is perfectly normal...enjoy the game..:)

2013 MBA's run hot

I bought and then returned an I7 MBA because I could not stand how hot it was running. On my lap it was actually painful.
I have a 2012 MBA with an I7 which runs the same applications without the fans coming on And without running hot.
BTW, what I run most of the time is multiple copies of Excel with somewhat large spreadsheets. Regardless, the Haswell processor runs noticeably hotter than its predecessor for the same given load. I also noticed that when the 2013 MBA was taxed in this manner, battery life went to hell in a hand basket.

For now I am sticking with my 2012 vintage MBA.

In Windows, there are utilities, sometimes even built-in to the machine to run the laptop in quiet mode. This mode tells the machine to never exceed a certain temperature, user-configurable, hence the need to reeve up the fan, this is accomplished by slowing down the clock dynamically. Depending what you are doing, u may not notice the slow down. Surprised Mac doesn't have similar.

Coming from a Gateway, I was shocked how quiet my July 2012 MBA is. I've heard the fans exactly once: when I was upgrading from Lion to ML. That said, YouTube is the most processor-intensive thing I do. I'm not into gaming.

The laptop will not just 'shut down'. Once the CPU reaches 100c, the CPU will start to throttle until it hits it's lowest clock. This is so the cooling system can gain control over the heat. (usually 800mhz)
