An important site! N4G may be a site that gradually improves your gaming knowledge and gradually educates you. However Gamasutra is a website for the proper gamers and developers in the industry who look for legit and in-depth news in the gaming industry. N4G may have news based upon the industry however it is polluted by many socialist, fake journalist and wanna-be journlaist who call themselves real journalist. You would often find unnecessary news about developers, seriously why do you want to know what Cliffy B says on his tweeter in reply to someone else? Therefore Gamasutra is a website to definitely check out if you are serious about the gaming industry.

Here's a good resource if you want to get a proper lecture for gaming industry insight. I wouldn't recommend this site though the information the author has for the site is worth a read. Basically the author is an industry experienced designer and gamer. He gives his advice, 'opinion', experience and insight about being a Game Designer. So if you are trying to be a game designer like myself, you need to read this. The guy has a lot of points however many of his points are really opinion and outdated, I would advise you not to buy too many of his words, if you are unsure, it is best to contact the user. For an example he claims that it is impossible to get a job role as a designer straight from finishing university, which is not true.
