> Some mobile games have a ton of installs and a very small amount of revenue per user. Those 27cents per install are a lot of money for those type of games and will even make some business models no longer feasible.

When you put it that way, Unity could have come out of this price change looking like heroes with better messaging.

Serious games pay the $0.27 fee moving forward, and (hopefully) that comes with some new value add for end users (such as contractually enforced no advertising, cross-platform something something).

Ad-supported games use a different engine with different rules, and end users get the “free to play” benefit.

(The retroactive thing is obviously bullshit; I wonder how many studios will simply refuse to pay and jump ship for future titles.)
