Ever since I released my Ninja Legacy game, I was approached by multiple review sites, with offers to do a review on it, IF I pay them $99...
I find that repulsive, to me, paying for reviews and sites that do that are worthless. Their sites are full of Ads already, they claim 2M unique visitors per month etc. Why are they demanding indie devs who are often poor to pay them such large sums?
Well, because apparently that is how bigger dev studios do it. They pay for good reviews, pay for app ratings and downloads to inflate their numbers and move up the chart/search.
I'm not successful so far, either my game is crap (which I don't think it is) or because nobody knows about it, so I cannot offer advice on marketing. I just posted some notices on Reddit on launch and twitter, thats it so far. Thinking of doing an old-school poster/business card spam-campaign around my city here.
