A games addictiveness is depended on how smooth the game play. I use to play swg, sure it has alot of girddin but griddin is actualy fun in that game , you can do it with ease and its a fun to talk to eachother as you grid, untell the changed it, SO!!!!!!!!! if the game has a smooth gameplay aspect its addictive, also it can be addictive if yo like the consept of it. ROleplay, and other thigns make addictivness as well.
