I will call it the "game for engineers" because this game is being played in every engineering colleges .I am a engineer myself and love playing this game at my hostel as well while seating as a back benchers in classes.
The best thing about this game is that you need no internet for playing multiplayer with your friends.Only one person have to create a hotspot and other have to join and then "game on".This is the one of the best concept according to me because it feels God competing with your known friend rather than competing online with unknown peoples.
If you want some game rivalry and wanna have fun with your friend group, then go on and install group;Just try once and believe me you will get addicted.
