The Sims 1, specifically the building. Playing the actual game was terrifying to me as a child but the best part was the music and silly things you could do with these blobs of pixelated dolls. This game had the absolute most horrifying noise for burglars and missed work days that scared my 8 year old brain to death. Its sequel, The Sims 2, is one of my top favorite games of all time and it is a timeless classic. The Sims 3 and The Sims 4 had their charms but theres no topping the old formula.
