Even though Blizzard apparently has "no major frontline release" for 2019, but it's still managing to give nostalgic fans something to tide them over.
Today, the publisher released the original Diablo for sale on DRM-free storefront GOG.com. As reported by Ars Technica, the release is almost identical to the original Diablo with a slight quality of life change to ensure the game will run correctly on modern displays. However, an option also exists for a GOG-built, DirectX version that includes more tweaks to improve resolution and other visual settings. It also includes some bug fixes.
