Dr. Mario on NES is one of those games that somehow never gets boring, even after all these years. At first glance, it feels like Tetris with a medical degree—you're dropping colored pills to match and eliminate viruses at the bottom of the bottle. Sounds simple, right? Then the speed picks up, and suddenly you're scrambling to line up combos before the screen fills up.

The real magic happens in two-player mode, though. Nothing beats the chaos of racing against a friend, sending garbage blocks their way every time you clear a row. Just warning you: it gets intense fast, and you might end up yelling at the screen when they sneak in a last-minute combo. The music’s weirdly catchy too—you’ll hum it for days.

It’s a perfect mix of strategy and panic, and somehow, it still holds up.
