A great number of games have in-game micro-transactions. The only current game I can think of (non-F2P) that totally revolves around micro-transactions is Destiny 2. There is a problem when the loot in a full price AAA game with paid DLC revolves around an outlet for micro-transactions. Basically, not all micro-transactions are "evil" and some are even required as the sole means of income for a developer. That is NOT the case for Destiny 2. The micro-transactions themselves are not the main issue, how Bungie has decided to implement and incorporate them into Destiny 2 IS the issue.
