Isn't it obvious? Runescape for me!
I've played MapleStory, SilkRoad, Voyage Century Online and Perfect World, and all of them are the same boring grindfests with similar gameplay except for one key gimmick, which makes me even gladder to play RS.
RuneScape has it's quirks and it's downsides such as the god-awful sound effects, but there are positives too. RuneScape is big without being overwhelming, and it's simple and fun, and the quests are a million times better, writing several never-ending stories in RuneScape's always expanding world. Plus I know a lot more people who play it and I've already played it for several years and I'm hooked. Even If I take a break from it, I'm always bound to return. ^.^
I know RuneScape isn't accepted well among the gaming world. But I don't care. I don't play mainstream games, I play games I enjoy. Each one to their own, right? For some of you, that's WoW. And for me, that's RuneScape.
Actually I'm still yet to try WoW, and I've heard it's good too, but my computer will never run it. Once I get a new computer, I have this Trial CD I can use. So, I'm not one-sided here. I rarely take sides over video games. For example, I have things I prefer such as Nintendo over Sony, but I still like both Nintendo and Sony.
