Possibly up there in the Top Five moments of any RPG, even good karma-inclined wastelanders found it hard to resist the temptation to chill on the balcony of Tenpenny Tower and watch Sheriff Simms' precious townstead burn in nuclear fire.
2. MEETING THE MASTER
Radioactivity plays a central theme in Fallout, but its most gruesome side-effects manifest in the original's big baddy, the Master. A heinous mash up of gelatinous gloop and melded mutant/machine parts, he envisaged an army of super mutants ruling the world. Instead, we nuked his cathedral real good.
