I used to play Maple Story a lot with my real life friends and although I enjoyed it WoW will always be near and dear to my heart. One of the main reasons Maple Story turned me off so much was because it was just a huge grind-fest where you would do the same thing every single day, I used to play back in beta and right after beta release where there where only a few PQs, not like today where they have several you can use to take you all the way to 70. Occasionally I will find myself still going back to play Maple every now and then, I like how they implemented that new Maple trading system where you can sell your things for NX; however it cant keep my attention for more than a few days. In WoW you have a lot of variety of what you can do and there are a lot of different things you can waste your time on. However, the only thing bad with WoW is the size of the whole program and how laggy it can be if you don't have a decent computer that can run it. So if you have a lot of space on your computer and you think you can run it, id recommend going to WoW it was a lot more interesting for me then Maple and for a lot of my real life friends who played Maple with me as well. But if you cant run WoW see if you can find a Maple private server that isn't so hard to level up on so you can focus more on actual game content rather than leveling up!
