I'm glad to finally see the release of Diablo I digitally along with compatibility tweaks for those who don't have an access to an older computer capable of running Diablo I properly. Although the game is a lot tougher than its sequels, it definitely is worth playing if your fan of the Diablo franchise or fan of the game like Path of Exile. GOG's rerelease includes two versions: the original vanilla version and the tweaked "modernized" version. The latter one features support for higher resolutions and includes compatibility tweaks for those running Windows 10. I'm running the game on Windows 7 and it runs both versions just fine on that operating systems. Heck, the classic version may even run on even older versions of Windows like Windows XP or Windows 98, since classic version's executable appears to the original one from 1996. Unfortunately, the online play via Blizzard's Battle.net requires the use of classic version at the time of this review and is unavailable on the modern version. Hopefully the support for Battle.net gets added in the future. I can't recommend this game enough. Hopefully this means Blizzard will release more of their games on GOG.
