@Kvedran most people today just don't care about anyone but themselves, that is why your first comment was thumbs down, just like this one will likely be thumbed down because i'm pointing out the bad qualities of billions of people on this Earth. :P
There should be mini-games that regain your energy,Skill points, and give you a few coins, and everyday you are in the highscore list you get maybe like 1-5 crystals
There should be Gun mods that you could buy, also maybe different types of grenades like regular grenades, flashbang grenades (Which make the area around them white for like 2-5 seconds, and poison grenades that take away like 5 hp everysecond in the cloud area!
