A song of Ice and Fire. A.K.A Game of Thrones some books took almost 10 years. it is almost 20 years for 5 books.
The thing is what is your goal? if the destination matters more than the journey you travel by plane, if not you travel by whatever is slow enough for you to enjoy and fast enough to not spend all your life on the journey. An AAA game is impossible for one man within only a year, let me be clear about it. NOBODY here will even attempt to do a DarkSouls in one year, that will be a year lost for nothing.
You said it is difficult to make your team... After reading you I can tell you that no professional will follow you, reason? they are many.
Your chance of convincing an indie with minimum experience is also around 0% as he will know all the trouble with this project. Remains other with no experience and full of dreams, they may follow you but this AAA project will fail more or less quickly.
My advice is the same as others said and I already told you. find those old game a make them, then make them better, then make them original. ex: Angry bird, I saw it 20 years ago during Qbasic demo somewhere. it was exactly the same game with just 3 or 4 levels and only squares, no bird, no image just squares. find something like this you don't need a year for that, if you can do well you will get some money and you will be able to pay for a team for your AAA game.
But there are few things that come in no time. Gamedev is not one of them.
