The Arqade, like the rest of the stack exchange websites, is all about getting quality answers to questions about all games. We strive for detailed answers that will help you and others to come who might have the same problem. While you may be able to get similar information on sites dedicated to that company or game, I don't think you will find that many other sites are as dedicated to quality as us. We are community moderated, and the community is very active in making sure that we remain a quality site. A lot of our members are also experts in game knowledge in the games they play and are willing to do in depth experiments or comprehensive data collection on games to discover how mechanics work, what the recommended strategies are, secret routes and achievements, and many other aspects of games that you may have trouble with. To sum it up, we are generally more dedicated to quality answers than most other sites are.
Here are just a few examples of the types of answers I am talking about.
Is Angry Birds deterministic?
What is the terminal velocity of a sheep?
What's the difference between life, health, armour and shield?
