Would this be a good investment?

Would it be a good idea to invest money in a video game companys' stock a little bit before they release a game that's going to be a best seller? (eg. if Bethesda was to release Elder Scrolls 5 in June, and you invested 6 months before). I just figured it would be a good short-term investment to do that, but I could be wrong. Any advice? And no im not talking about investing in a company such as microsoft of sony where video game sales are a small fraction of their entire company, but a company thats entirely video game based.
