Sonic the hedgehog is a game that was truly ahead of its time. The music in sonic 1 is so iconic, whenever you hear it you know what game it's from. The same can be said for the sound effects, whether it's collecting rings, finishing a level, or almost drowning. Each sound is truly iconic and special in its own way.

Another thing about sonic 1 that's amazing is the level design. The levels are full of spaces to explore and different routes to take. It really does baffle me how on Sega's first try they managed to get everything so right.
