From the opinion piece:
Last year, I pointed out how many big publishers came crawlin’ back to Steam after trying their own things: EA, Activision, Microsoft. This year, for the first time ever, two Blizzard games released on Steam: Overwatch and Diablo 4.
They’re exactly the same for me, 50% off from 59,99€? If the pricing is not in EUR or USD the comparison between pricing become much harder than because it’s a whole other world with regional pricing and currency conversions etc. that I don’t fully understand. It’s most likely the case that Steam does a better job at calculating the pricing into your currency than other storefronts.
Yes, it seems you are right. Nonetheless, even at equal prices, isn’t it surprising?
