Now we talkin 'good' review, or just review that gets a ton of views? Because the later is ridiculously easy.
Watch this: _______ is complete crap and one of the worst games ever made, if you play that game, you are a sap and have horrible taste in games! Replace _______ with any popular new game, for example inFAMOUS would work fantastic right now, and you're done.
Voila, make a topic with those words and you're guaranteed at least two pages of debate, minimum. Doesn't count if a mod closes the topic. Writing a good review however requires actual thought and effort and will get half the views. What's the point right?
