A good LOTRO level guide should have, first of all, a solid sample that you can check for yourself and decide whether it suits your needs or not. It should look like a solid walkthrough for the quests in the game, locations and NPCs you need to see and it should also have a good system of maps. Another feature of a good LOTRO level guide should be a system of links to various LOTRO helpful sites and forums which should cover the rest of information needed in order to improve your Middle Earth game experience. Last but not least, a good LOTRO level guide should have a "100% money back guaranteed" if you don't like the product. This feature usually expresses the author's confidence about the effectiveness of the guide and certainly gives you the safety of getting your money back in case the guide turns out to be a rip off.
Now that you know how to spot a good LOTRO level guide, feel free to start your journey throughout Middle Earth and take part to one of the most pleasant online experiences that exist.
