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 have been thinking of whether there was a pokemon mod that does something like this.
I’d like something that gets rid of trade evolutions and puts all 151 in a single game.
I’m sure it’s out there. So, I guess that’s my half assed attempt at an answer.
I swear every time I start looking into a romhack that claims to just be a mostly vanilla QoL update they always add in a bunch of random stuff to “fix” the difficulty.
Like, yes I am aware the games are incredibly easy. They’re for children. I originally played most of them as children. Just let me get high and stomp all through FRLG with a perfect-IV Feraligatr and the Gen 4 physical-special split. If I wanted to do Nuzzlockes I would… Do Nuzzlockes. If I wanted a game with difficult gym leaders and level caps, I would go play one of the thousands of romhacks that have that.
Have a search for “universal pokémon randomiser” (there are apparently loads of different forks of it now), it’s main feature is to randomise which pokémon you encounter, their types, moves, etc, but you could skip that and just set “change trade evolutions” and “catch em all mode” to get exactly what you want. I would recommend playing it randomised though!
There’s one called simply Pokemon Blue - 151.
A modder named Drayano has pretty much defined this category of ROM hack and I think has his own version of every major game from generations 3-6
There’s probably romhacks out there that do that.
