Diablo. The OG. Yeah, I know that most people prefer the sequel and don't get me wrong it's a great game (I've been playing it lately with the Median XL mod) but it just doesn't have the same dark gothic vibe the original has. Some call it slow and clunky, I call it precise and methodicalijh
I know absolutely what you mean, i have the Game since i am a Kid, but i first played through it when it came to Gog.
As mentioned by Spike, sometimes it is the Simplicity that makes it stand out
The Atmosphere is incredible, compared to the Sequels, you are also actually afraid to die, as the Possibility is much higher.
It also very nicely done, from killing some minor Evils in the Cathedral it becomes more and more insane as you come closer to Hell.
DevilutionX makes it also very comfortable to play, you can throw your Save Game to your Mobile Phone and many other different Devices and proceed playing, it plays incredible well with a Controller.
The Game has become something i play constantly, with bigger Breaks inbetween.
Diablo 2 and even more so the Sequels are hectic, meanwhile in the first you proceed more carefully.
And don't get me wrong, i really like Diablo 2.
But to get other Games i replay often:
Turtles in Time, it is just so upbeat, at least once a Year i complete it.
Monkey Island is also a Game i somehow did beat nearly once a Year.
Doom is something i can play several Times a Year, Doomworld also delivers an unlimited Supply of new Maps.
Personally i like Doom 1 with its Level Screen and Episodes more than 2, the second one is also very brown.
Because of Gog, i played this Year the first Time through Resident Evil, three Times.
I am sure this will become a Game i replay every Couple of Years.
And yes, there is something about the bad Acting and Simplicity of the first.
I also played through the second and third.
Parodius (SNES) also the Music that is so fun and the colorful Levels.
The only Shoot em up i am good in and i ever played through, but ok, like Turtles in Time i am playing it since the 90s.
The Sequels are too busy for me.
Super Mario Kart, love the Music.
Metal Gear Solid
Super Mario World
Simcity 2000
Starcraft
Tomb Raider 1 & 2
There are other Candidates that still have to stand the Test of Time, as Streets of Rage, Sonic 3D Blast and Daggerfall.
Hmm mentioning the last, Morrosind and Skyrim are also such Candidates, as i never really stopped playing them, i only have bigger Pauses ^^
