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.


OpenRCT2 is 100% the definitive way to play Roller Coaster Tycoon 1 & 2.
But I would never recommend a new player try OpenRA. The game has stellar multiplayer support but they just can’t figure out the campaign scripting at all. Go with the remaster collection instead.
Still? I haven’t played OpenRA in several years and assumed they would have fixed it by now.
Then again Red Alert 2 is even less supported than it was the last time I checked, so I’m guessing their focus is mostly on the multiplayer side of things.
