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.


I could argue that experiencing the Groundhog Day bug builds character but… no. Nobody should have to deal with that.
Admittedly, a few tactics like filling your base with laser rifles to make attacking aliens spawn unarmed no longer work. But honestly, an experienced player treats base attacks like bonus levels anyway so it’s not like much of value was lost. Besides, you also now get all the loot from big missions and not just the first 128 items.
Also, UFO now actually remembers your difficulty setting and doesn’t revert you to Beginner after the first mission. That’s different but better. I probably should’ve mentioned that separately in my first comment.
