Gramers are sort of casual players. They usually play the madden and other sports games ,First person shooters and any game with a lot of explosions in it. They have very short attention spans which means they can't set down to play a long fulfilling games such as RPGs or action adventures and it means they almost never finish their games. Gramers are not like regular gamers, most gramers began playing games right around the time Playstation took over the market and starting producing more sports games and more mature games that would appeal to larger audiences. Before Playstation made games cool these gramers (mostly jocks) were non gamers that would make fun of real gamers, they would say "games are for kids" or they would say "dude, games are so gay".
