Hi, Silverforce. As someone who works for a film production company, I can tell you that video game marketing is very similar. Essentially, it all boils down to the quality of your game. Is it fun? What sort of demographics are you targeting? Are there similar games out there? Is it a free game or a paid app? These are just a few questions every player has on their mind, and questions you should have answers for. There are TONS of legitimate review sites out there looking for quality games to review, because those games boost page views for the site, which is a win-win for all parties involved. Since your game is an indie production, a few to check out would be Indiemag, Gamejolt, IndieDB, App Spy, etc. A simple google search for "indie game review sites" will provide you all you need. There's also Reddit, where you can post to r/indiegaming, r/androidgaming, r/pcgaming, r/steam, and more. You can also contact "Let's Play" youtube channels to review your game. DON'T limit yourself to a few forums and "hope for the best", and inversely, NEVER pay for a review. Nobody frequents paid review sites, because they're crap. Do your research, contact all the resources I mentioned, and don't give up until you start seeing your hard work pay off.
