Growing AAA video games is getting increasingly more costly every technology.
Simply attempt to evaluate the credit of a recreation made 20 years in the past with a brand new one and also you’ll see that the individuals engaged on them has greater than doubled.
Additionally think about how a long time in the past video games was completed and absolutely examined in only a yr or two (let’s say, Remaining Fantasy as an RPG instance), in the meantime Xenoblade Chronicles 3 has been in growth for five years and the workforce will proceed to work on patches and DLC for not less than one other yr.
However, recreation costs haven’t modified that a lot, with solely a ten USD enhance within the final 20 years (Nintendo of America), and most of the people aren’t keen to pay extra for larger and higher video games.
That’s why corporations are at all times in search of methods to maximise earnings by way of DLC, cosmetics, loot-boxes, subscriptions and so forth.
