A cosplayer can do this all by his own tough: Creating a costume, kid cosplay costumes promote a his favourite game on his various social media channels and deliver the passion and knowledge for the perfect character interpretation at a gaming convention for example. Even if it’s cool to work for a well-known gaming company, don’t do it for free. Creating a costume, taking and posting countless pictures and videos and turning a fictional character to life is something incredible special and very beneficial for promotion work.
