What's the point of WoW?
The point of the game when you're leveling is to explore content and accrue levels. The choice of whether you'd prefer exploring content or just gaining levels is up to you. But until you get to the endgame, you're just enjoying stories, checking out the landscape, and gaining levels. That's the point.
You accrue levels by gaining experience points. The more points you gain, the higher your level climbs; the final level is level 85. How do you get experience points?
What are quests?
Defeating NPC bad guys, often called mobs
Exploring the map of each area
Achieving other objectives, like winning a player-versus-player minigame
Most of the flow in the game will be determined by quests. A friendly NPC with a quest for you will have a golden exclamation mark over its head. Right-click that NPC to see the quest dialogue. Read through the quest to understand what the NPC wants you to do. Accept or decline the quest at the bottom of that dialogue.
Most quests are split up into basic categories. Kill a certain number of mobs, collect a certain number of materials, or do some other basic task. For example, you may need to protect a friendly NPC while it moves through the area.
The quest text is fairly important. It tells you the in-game story of why you're completing the task. ("Help me, Mr. Adventurer, a rabid wombat ate all my chickens! Kill the wombat so I can grow more chickens!") Even more critical, the quest text will tell you where to find the particular kind of mob to kill.
You can also find the objective locations on your world map. Hit M to pull it up. On this map, your quests will be labeled with handy numbers. Mousing over the quest title will highlight blue areas on the map; that indicates you can find the objective somewhere in that zone.
We won't talk a lot about fighting mobs here, since the in-game tutorials do a pretty good job of explaining that. However, some important tips when you're fighting a pack of creatures:
What are usable items?
They respawn. That means after you've killed a group of bad guys, you should be careful about lingering in the same spot. Those monsters will be back, and you don't want to be caught in the middle of them unprepared.
Mobs drop three different kinds of items. Right-click a sparkling dead mob to pick up its dropped items. Items will either be usable items, vendor trash, or quest items. Quest items are usually an objective. When Bob tells you to collect 14 pig livers, the white quest item Pig Liver is the goal of the quest. Vendor trash is gray items that you sell to vendors to get money, while usable items are a something in between.
Mobs drop magic items and reagents as usable items. Magic items are the gear you wear on your character to enhance its abilities. Again, this is pretty well covered in in-game tutorials.
The other kind of usable items are crafting materials. Players use these white items to make other kind of gear, usually on par with the items that drop from mobs. Understanding the crafting system is a big, complex discussion, but if you get any white items, swing by the Auction House and see if you can't sell them for a little extra gold.
Of course, you don't have to do that if you don't want. You could
just sell white, usable items to a vendor without any real negative repercussions. While the crafting game is fun, it's not a core part of leveling or advancing your character. You'll be just fine without it.
Not much can go wrong
In the end, just relax and do quests and kill mobs. You're allowed to wander around the map and get lost. You can't really do anything that will permanently screw up your character, so don't worry about doing something wrong. WoW
is thankfully not built that way. Just take your time and explore.
