Forgotten Worlds on the Sega Master System is one of those weird, cool side-scrollers where you play as a floating warrior with a jetpack—kinda like if Contra and a space opera had a baby. You’re blasting through alien landscapes, spinning your character 360 degrees to shoot in any direction, which felt surprisingly smooth for an 8-bit game. The bosses are massive, screen-filling beasts that take forever to whittle down, and the power-up system lets you buy weapons between levels with in-game currency. (Pro tip: Save up for the homing shots.)

It’s got that classic Capcom arcade vibe but with a strange, almost dreamlike atmosphere—like you’re fighting through some forgotten alien civilization. The music’s eerie synth tracks still stick in my head years later. Just don’t expect it to hold your hand; this one’s tough as nails.
