Ah... sound like i got to be a multimillionaire in order to publish my desire game.
Or you just need a good business plan to get investors to foot the bill.
I might say that it could be done for quite a bit less then $1m. I was the tech lead on a top 10 iOS game for my company and there is no way it cost $1m to make. Probably in the range of $300-$350k. Granted the art in Clash of Clans is better then ours which is going to help drive up the price a fair amount.
