Destiny’s newly introduced microtransactions appear to be off to a hot start, at least on one platform family. As spotted by Game Informer, several of the top spots on the PlayStation charts for paid add-ons are taken by Destiny’s new Silver currency. You can see this chart on the PlayStation Store’s website.

The only add-on that’s selling better than Destiny’s Silver is The Taken King expansion itself.

The most popular Destiny Silver bundle is the $10 package that comes with 1,100 Silver. The others, 2,300 Silver ($20) and 500 Silver ($5), are also both in the top five on the chart. The only non-Destiny add-on in the top five is Minecraft: Story Mode‘s season pass.

That Destiny’s new microtransactions are performing well would be no surprise to Cowen & Company analyst Doug Creutz. Earlier this month, he predicted that Destiny’s microtransactions could generate “hundreds of millions” for Activision and “broaden the revenue opportunity for what is already a very successful core franchise.” Exactly how much revenue has been generated by Destiny’s microtransactions is unclear, though Activision may shed some light on the matter next week during its earnings briefing.

Players can spend Silver to buy emotes, including new ones released this week as part of Destiny’s Halloween festivities, as well as some other items through the Eververse Trading Company in-game store. Whether or not Bungie ever sells anything beyond emotes for real-world money remains to be seen.

No information is available regarding Destiny’s microtransaction sales on Xbox platforms.

Microtransaction systems in AAA games is nothing new. Two recent examples of games that offer microtransactions include Metal Gear Solid V: The Phantom Pain and Assassin’s Creed Syndicate. In fact, it is rare for such games not to have them, as is the case with Star Wars Battlefront.
