You’d need to have deep pockets to have your homebrew made …
If licenced - $50k starting price plus music and actors on top of that. Everyone is holding their hands out. If you can even get the licence in the first place (you probably can’t)
Then say you wanted to make 100 games that you could sell.
Let’s throw a contract price of $5500 for a stern pro level game. (Hey, could be $5000 … adjust the calculations to suit)
You need to pay probably 30% up front before they even start. So that’s $165,000 (plus any tax) for the deposit.
Then you’ll have to pay the balance of $385,000 plus any tax as soon as they’ve finished.
Now you have $550,000 worth (plus all the licencing costs, if any) games in a warehouse (that also costs a lot of money to rent) that you have to try and sell.
At the end of the day, you might make say $1000 a game?
So you’re investing $550-650 thousand dollars, to make $100,000. Presuming you sell all hundred games. Depending on the retail you’re asking, you’d probably need to sell 90 games just to break even.
You’d need to be able to finance 650,000 bucks up front and sit on that amount for 12-24 months. Of course if you loan the money, you have interest on top of that.
And if you don’t sell all 100 games - you lose your house that you borrowed against.
Gonna take some balls to do that!
