Okay, to tell you the truth, I'm a returning maple player, but if you don't mind that. i don't mine sharing some things about the game.
Maple is "A GOOD GAME" but it's your experiences in the game that's going to count the most. if you are definitely new to the game here's some tips I can share with you that get me through the game.
1. Always do research about a character first. There's no such thing as one fun glass. That is determined by you. Also, don't fall into the whole that this one character is the best because not everyone likes to be a theif, magician, bowman, or warrior. Always make sure that when you do research you say. "Okay! This class seems more like me." Maplestory is all about " How you make your character and go throughout the game." not what everyone else thinks you should be. I had run into many cases where people quit the game because they listened to other people saying that this class is better than the other. When that class didn't suit them yet. I did a lot of reseach and the characters that always suit me is a warrior, pirate, and a bowman. I like close and personal. Making money as well is me too. So if bowman suits you, do a little research. There are plenty of guides and don't forget to compare guides.
2. Server that will suit your needs. Let say you want to be a lone fighter than the new servers is great for you. if you want someone to be friends or talk to then the servers before the new is best for you. Also make sure you pick a server that can run on your computer. If you pick Scania and you lag a lot, then it's not great to make characters there.
3 . Make a Mock Character first. A mockery character is a character that even if you made a mistake, it really doesn't matter because it's not your main character. The purpose of a mockery character is to gather information, get use to the system of the game, and develop an understanding before you make a main character. Mockery characters can later be deleted or used a storage when you feel you are comfortable with the game.
4. Never beg in the game nor feed beggars. It's very very easy to make money in this game. All it takes is time and determination of killing simple monsters. Always balance yourself between trainning and money gathering. You can't make money if your spending too much killing monsters that are too high level than you. Also don't feed those who beg to you. Some beggars would ask for a large amount of money. If they wwould just train and fight, they can get that amount at the same time they beg.
5. Be warned, not everyone is friendly. You might encounter some rude people in the game. there are better methods of handling these people, but I'll tell you this. Don't pay heed to them. Ignore them and move on. Some people just want attention. There are many other methods to dealing with these people, but I don't want to bore you with all of it.
Well, that's all I got to say to you. I hope this helps.
