Well, there's nothing really holding you back, except your fans...but when it comes to being new or still learning, if you know how to implement the features and if the story is great, people will look past that fact. Plus, you'll be sure to meet a lot of new people in the game development section. Either way, there will be people who will support you and will want to help you, and there are more possibilities when it come to Game development, and it really does seem like a game, so I say go for it, it was a thought put into your mind because that's what you really want.
