Well, that took some time. The Epic Games Store now lets you wishlist games.
On a game’s page, there’s now a small heart icon beside the buy button. Click on that and it gets added to your wishlist.
The wishlist, on the Epic launcher, is a bit hidden. You have to click on your profile, then select wishlists within that.
The Epic Games Store blog notes that there are plans to add email notifications on the games you wishlisted should it get on sale, or now available for pre-orders or purchase. It’s not live yet, so now the wishlist is just a literal list of games you wish to buy.
The Epic Games Store is still isn’t as feature-rich as its PC games platform counterparts, but hey, progress is being made.
