faisalbaba unfortunately yes, Asphalt Extreme requires internet and this is a negative for me at least...Personally games that required internet i don't like them(not from the experience that provides them) but from the way that it wants internet..I mean that it has an impact on battery life when playing with WiFi than playing without internet or WiFi because the battery will last a little longer! And in addition if you can't find a WiFi somewhere you cannot play! Another negative for WiFi games!
I hope helped you!
