So we should recycle the same shit over and over for the sake of playing it safe? Sounds like a terrible plan.
Not exactly. Cost justification isn't necessarily between a developer and publisher, but between a buyer and the product as well. If you take a game like
Closure and pour an extra 1,000,000$ into it. . . the end user isn't going to get that much more bang for the buck.
Regardless, pouring a lot of money into chance endeavors also sucks. Ever fund a project with your own money? Or started any sort of business and been responsible for someone's salary? With a family? Perspectives change on what type of chances you want to take with what ratio of cash you have to spend. A company can be that times 1000. But, hey, I guess a CEO could turn the statement around and say anyone not opening a business is playing it safe with their life, and that's not a good plan either.
Just to give you a virtual charliehorse, I would like to passively reference the irony of your "recycled shit" statement and point to your Bladeru. . . I mean, Snatcher avatar*. As if Kojima doesn't recycle other concepts much less his own series (Metal Gear).

Most everything we're surrounded by doesn't live up to its potential and plays it pretty safe - the clothing we buy, the power grid we use. . . games aren't much different.
People actually like crappy games, too. Sometimes they're just looking for something different in a game. Sometimes they just have crappy taste. Don't be mad at the developers. Be mad that there are that many people walking around to justify the cost.
*Or is that an
A-ha video?
