Well, early on you are attacked by pirates and washed ashore and meet some old guy. You then save a whore from her certain doom which lets you get a grasp on combat and the controls. First thing to notice is that you can join guilds at any level, not 20, so make sure to get a guild invite from one of us. Then you will end up killing some bosses, which are easy and end up in the Tortage area and be level 5, so the first quest - talk to the blacksmith and run to the left and get the bricks, its easy and if you can get a group with some friends starting now leveling will be a breeze.
Second you will notice by now that you have been learning skills when you level! Unlike WoW, you don't have to train skills and you will gain them most levels. Feats begin at level 10 and you get two every 10th multiple after that such as 20 and 30 (This is what we have noticed so far). Also note, early on the skills might not auto replace so if you get a rank two or higher, make sure to check if it was auto replaced.
Third is that you will sooner or later be sent to the inn and have a chance to do something called Night quests. These quests are single player only and as such have much reduced framerate for you tiny computer users. These are usually easy depending on your class and most can be completed within 1 or 2 levels of the requirement.
Fourth, there is pvp in certain areas such as the underhalls and white sands!!! You will go to these places later on around 15 and it definitely helps to have a group or else your going to be a target. Notice that stealth (everyone has this) is really good at these locations because it will let you get away really quick. If not, just sprint and you shouldn't take too much damage. Instance jumping is useful if you can outload them, if not your screwed.
So far this is all I have to say, I will try to update this soon!
