Just don’t buy them.
This has been the standard line on microtransactions for years now. Whenever a game announces that it’s employing some microtransaction scheme to nickel and dime its user base for some of that sweet, sweet secondary revenue, and whenever fans upset by such an announcement have worked themselves into a froth, cooler heads have always chimed in with the clearheaded advice that we should simply not buy the micro-priced digital doodads. Problem solved. Play your game, ignore the in-game marketplace, and get on with your day.
In fact, mitigating this reaction and encouraging players to not buy their product seems to be part of publishers’ marketing strategy in these situations. They’re always quick to point out that the digital gewgaws on offer are purely cosmetic and don’t affect gameplay; that buying them is, in other words, entirely unnecessary. And when this isn’t the case, when things like weapons, abilities, and XP boosts are available for purchase, the publisher will adamantly remind us that all of these items can be unlocked through “normal gameplay,” no purchase necessary.
If you don’t want to buy it, don’t buy it, in other words. Vote with your wallet. Stop buying these things and publishers will stop selling them. It all sounds so simple.
