When I started playing Runescape, I was immediately hooked. Although the gameplay was not the best, I was so addicted I wasn't finishing homework and it was effecting my social life, until I just upped and quit. Then, my friend told me about WoW, and I downloaded the 10 day free trial- and I was hooked to that. The gameplay was still pretty much a grindfest. All the games I tried between that time period, namely Shaiya, Maplestory, Tibia, and Perfect World, none of them hooked me, but a lot of them were better games, like Perfect World. (In my opinion.) What makes a game addicting? Runescape seems like the most boring of all the games, click on a monster and pray that you kill it, but it was also the most addicting. WTF?
