The shift in mobile gaming in how developers / publishers could nickel & dime different features seeped into paid content. The separation was most of these games were free-to-play or at least ad-supported.
Now, it’s just a double-dip. The filthy casuals will wait while the dedicated fans will pony up their wallets if they want a better product. The one that infuriates me most is exclusive or pre-order content that becomes available to everyone a few months after launch.
