To clarify, if I was introducing someone to the Diablo series for the first time and told them they’d have to start on the first one. I wouldn’t want them playing the bare vanilla version. There is a Bezelbub mod out there that gives the game lots of QoL improvements, you’d be thinking you’re playing a build of Diablo 2 before its final version.
So, if I had to tell anyone what the best way to play that game would be, it is the Bezelbub mod. That was how I’ve beaten the first game anyways.
if you’re playing FFXIV, especially on Linux, don’t bother with the official launcher/updater. Use XIVLauncher, hell even use that if you’re playing on Windows. Updates a hell of a lot faster plus you also get the dalamud stuff which adds a few quality of life plugin improvements.
