There are several ways that you could be getting reliable gaming related news however if you have access to the Internet then you will find that nothing beats the power of the Internet in providing you with not only reliable but also relevant and instantaneous news related to all areas of gaming that you may be interested in.
It would be cool if you can spend time researching different websites to identify those that can provide you the kind of information that you may be after as not all websites may exactly have every type of information given that everyone is different and no two players of games would have the exact same type of requirements with regards to information and news related to various genres or categories of games.
A good way to determine whether a website like ArmchairEmpire.com would have appropriate information for you will be by actually visiting it and also by checking how many others visit them as well. You may also want to check the social media presence of these websites as those who are active on social media tend to have better information to share with you. However that does not mean if a website does not have a social media wing that it would not have appropriate information as it all depends upon what you are after.
