Here are a few choice quotes from cell phine reviewers in 2013:
I currently own an iPhone 6, so imagining these games with bigger pixels is not enticing at all.
Engadget said:When we mentioned that the Mega uses a 720p display, you likely already assumed that it would offer a horrible viewing experience -- pixel density aficionados will scoff at the phone's 233 ppi, and indeed, we had the exact same expectation going into this review. However, it's not actually as bad as we had originally imagined. If you look close enough at the screen, the pixels definitely come out to say hello, but larger screens are also designed for longer-distance viewing than your run-of-the-mill 5-incher. So, from an ideal distance, the Mega is surprisingly decent. We would never turn down a 1080p display when offered to us, of course, but our overall experience wasn't nearly as disappointing as anticipated.
CNET said:That lower screen resolution is a noticeable hit -- just 720p HD (1,280x720 pixels) versus the 1080p HD (1,920x1,080) we see on many premium phones with 5-inch screens and above. Most native icons scale to continue looking crisp on the Mega's display, and Web sites look fine, even better than OK since there's a lot of room to read full desktop and mobile Web pages alike. Yet hold the Mega next to a phone with a higher-resolution display (even another LCD like the HTC One or iPhone 5) and you'll see that the same streaming video has much more detail, richer color, and a lot less noise than on the Mega.
What's the best looking mobile game you have played on your high resolution phone?
