Metal Gear creator Hideo Kojima says he's worried that the next entry in the series, Ground Zeroes, will be so mature that it might not sell.

In a roundtable interview with Video Gamer, Kojima explained, "Over the past 25 year I have tried to work with the Metal Gear series to introduce more mature themes, but really it hasn't gotten there yet. Compared to movies and books it still has a long way to go. That's precisely what I want to try to tackle with Ground Zeroes. Honestly I'm going to be targeting a lot of taboos, a lot of mature themes that really are quite risky. I'm not even sure if I'm going to be able to release the game, and even if I did release the game then maybe it wouldn't sell because it's too much. As a creator I want to take that risk."

This is an interesting fear, and we wonder if the new Metal Gear can really push the envelope further than series like Grand Theft Auto, Call of Duty, and Manhunt already have. We'll just have to wait until Metal Gear Ground Zeroes release to see if the game is really as controversial as Kojima believes. Unfortunately, we don't yet know when that release will be.
