To make a game and publish it, you have to consider some things.
-Most platforms cost money to host your game. Steam takes 30% I believe, for example. This is to host multiplay(security as well), installs, statistics, and a brand that attracts the largest audience.
-publisher debt - this is the money you have to pay back to the publisher upon the sale of your game. games, like many creative endeavors, are done on borrowed money if not crowd-funded. The creators don't see a dime until it is a success. Higher cost means faster recovery.
-Finally, after all of those costs are taken care of, you can start to profit. With hardware costs, service costs, and software costs all increasing, I am not surprised that game costs are rising as well. Making a game is one of the most expensive and complicated creative endeavors that you can embark upon.
I think that if a game gives you a ratio of one hour of great entertainment per ten dollars spent, that is a good game. More than that, that is a great game. Many games give you way more than your money's worth.
