If I was a big game company, I'd be glad that anyone in my office came up with an idea that might revitalize sales and maybe even draw some new customers. Especially when my main competition is the video game industry, which grosses more annually than movies do.
And if I was going to make an all new game setting and lie to people about it, I'd say it had been in production for years and was the pinnacle of creativity. That way, I could avoid telling 11,000 current customers that this product was better than what they came up with.
