When it was revealed last week that Australian currency would be supported on Steam come November 21, the good news was accompanied by a worrisome caveat. If publishers and devs failed to update Steam's database with a specific Australian price, their games would no longer be available to purchase for Australian customers.
It's now November 21 in Australia, and as promised, Steam is showing AU dollar prices across both its client and its website. But many publishers and studios, including big names like Microsoft Studios and Konami, have apparently failed to provide an Australian price, meaning the likes of Fable Anniversary, Ori and the Blind Forest, and Metal Gear Solid V can not be purchased by Australians at present.
For example: Ori and the Blind Forest: Definitive Edition still has an accessible store page for Australian viewers, but the option to purchase the game is absent. Of course, if you've already purchased any game in the past it'll still be in your library. But unless the likes of Microsoft and Konami (not to mention the potentially hundreds of other studios and publishers) go in and set a price manually, the games are impossible to buy.
Plenty of other games aren't available too, as per Kotaku, including Undertale, Return of the Obra Dinn, Celeste, Don't Starve Together... the list goes on.
As for what's available, at a glance the new prices seem generally reasonable, though I've not checked every single game in Steam's inventory. To pull one example out of the air, Assassin's Creed: Odyssey is AU$79.95, while the US price is $59.99, which converts to roughly AU$83. I'll keep an eye out for any ongoing anomalies. In the meantime, I've contacted Valve or comment.
