Step into any candle store and you'll be met with walls of scented wax with names like Summer S'mores and London Calling. You'll look at the label and think, "Huh, I can't imagine that scent could exist in this wax," before popping the cap and drawing a deep breath. Suddenly you're a teenager again, sitting around a campfire and lowering a marshmallow into a fire. Suddenly, you're aboard a majestic ship packed with crates of fragrant teas in search of the Isle of Lavender. Candles can transport you to a memory long lost, or bring you to a place you never knew existed. And, when mixed with video games, candles can fully immerse you into the world on the screen.
Light a wick or two and suddenly you're there, seeing the sights with your eyes, hearing the sounds with your ears, feeling the rumble with your hands, and, yes, smelling the smell with your nose. Scent is a criminally underutilized tool when attempting to evoke emotion, but it's not that difficult to bridge the gap and bring one more sense along for the ride.
