"In a newly published forecast of the global game market, Juniper Research concedes that developers are "effectively encouraging a form of in-game gambling" with loot boxes and using that addictive potential to "extend both the lifecycle and engagement of games titles to their audience." These kinds of non-traditional money-making techniques are a practical necessity for developers squeezed by increasing costs and stagnant or declining up-front game prices, Juniper says."

Sorry, like what Jagex said on the Monetization thread, TH is a pratical necessity for them squeezed by increasing costs and stagnant or declining upfront game prices.
"one analyst sees spending on loot boxes increasing by over 62 percent in the next four years to become a $47 billion piece of the industry. By then, loot boxes will represent over 29 percent of all spending on digital games, the analyst said, up from just under 25 percent currently."
People are expected to spend 62% more on loot boxes over the next 4 years too.
