Poseidon Wars 3-D on the Sega Master System is one of those weirdly ambitious games that tries to do underwater naval battles in 3D—and honestly, it kinda works? You start off picking your fleet (I always went heavy on subs because, well, underwater), and then you're thrown into this murky blue battlefield where ships actually move in three dimensions. The graphics are blocky by today's standards, but back then, seeing depth in the water felt like magic.

It’s not just about blasting everything—you’ve got to manage depth levels, torpedo angles, and even sonar detection. The first time an enemy cruiser slipped past me because I wasn’t watching my depth gauge, I yelled at my TV. The controls take a minute to get used to, but once it clicks, there’s something satisfying about lining up the perfect torpedo shot while dodging depth charges.

If you’re into retro strategy games with a twist, this one’s a hidden gem. Just don’t expect modern polish—it’s janky, loud, and totally its own thing.
