We live in a world where reviews are taken into consideration when purchases are made. One of the consequences of this is that companies will give away copies of media for review, or sometimes just outright pay for reviews. This practice is immoral, as it is plain manipulation.
Luckily, people have become aware of these practices, and we have this idea of disclosure: if you got this game for review purposes, or if you get paid for these reviews, you need to state this clearly. This is a good step forward.
These guidelines are for public use, if you want to use them yourself, go ahead. If you don't, then don't.
Any potential conflicts of interest must be clearly stated.
This includes (but isn't limited to):
'Clearly stated' means that the disclosure must be in a prominent location, and not hidden.
<em>DISCLOSURE: blah blah blah</em>puts it in italics) at the top of the review/article is ideal.
Any changes to these guidelines will appear here, with the date the edits were made.
