Rampart on the Sega Master System is this weird little gem where you're constantly juggling castle defense and cannon fire. One minute you're frantically placing walls to patch up holes in your fortress, the next you're lining up shots to blast your opponent's towers to rubble. The turn-based pacing makes it feel almost chess-like, but with way more explosions.

What really gets me is the puzzle-like tension—you never have enough time or blocks to fully secure your base, so every decision matters. Mess up your wall placement, and you'll watch helplessly as enemy fire pours through the gaps. It's simple, but man does it make you think on your feet.

Still holds up if you're into that old-school, "one more round" kind of strategy.
