Is it too old to use an iphone 4 at 2013?

I just bought an iphone 4 $423. I just want to use it for entertaiment like videos, fb, insta, twitter and etc. Also for gaming like nba 2k13, asphalt 7 etc. Can i play nba 2k13 or asphalt 7 on my iphone 4 without lag?

U kidding me? The only way a mobile phone is too old is you struggle lifting it off the ground.

What the? U spend over $400 on an iPhone 4? I got mine for free because it's older… For that price you might as well have gotten an iPhone 5… Sorry but i think you got ripped off

Yeah it's fine, I only just upgraded to the iPhone 5 last week and regret it. I want my iphone 4 back
All the apps and software still work perfectly fine

No, alot of people still use 3GS today, many will still be using 4 even 2 years from now. If you want to play the really high end games then they may consume more memory so latest version would obviously handle that better, but everything else would be good.
