Fond memories of this as a kid. I remember after playing it for a while with friends and coming across BoBaFett's trainer and DooM-Gaze's (sic?) trainer enabling god-mode, fast spellcast, maxed stats, Godly Plate of the Whale armor, King's Sword of Haste, dropping elixirs all over town around Deckard Cain, etc. I was legitimately scared at my age to step into the cracks of hell to go after Diablo when they opened behind Pepin's hut. And the Butcher... kept all the lights on for that quest...
As a 10 year old, it was the first "adult" game I played (alongside Leisure Suit Larry). Dropping the turn based style and keeping classes more simplistic was an excellent decision. It's what introduced me to the online world via battle.net and PKing (player killing) was a joy in itself. Clans, online friends, and memories all shortly followed. Loved reading this.
Diablo 1: still better than the 3rd.
