Remember when Sonic and Knuckles first dropped on the Sega Genesis? This one's a classic—you get the full combo of Sonic 3 and Sonic & Knuckles locked on together, just like the good ol' days. The levels feel huge compared to earlier Sonic games, especially with those sweet new elemental shields (the fire one’s my favorite—bouncing off enemies never gets old).

And Knuckles? Dude’s a beast. Gliding and climbing walls changes everything, especially in those hidden areas you couldn’t reach as Sonic. The music slaps too—Ice Cap Zone’s track still lives in my head rent-free. If you never played it back then, now’s your chance to see why this combo was peak Genesis Sonic.
