Completed on the Sonic Origins collection. I’ve always dipped in and out of trying to beat Sonic 1, but constantly fell out of it (like many I assume) when getting to Marble Zone. All 3 acts of Green Hill Zone are just so much fun to play, there not too difficult, you can go fast, its exactly what Sonic should be. Then comes Marble Zone and I am almost immediately filled with a mix of frustration and bordum. Its just so slow and tedious and opposite of what Green Hill is. And once I lose all my lives to something stupid crushing me or lava, my time with the game usually ends there. This time though, I played as a part of story mode on Sonic Origins so lives weren't a barrier. Sonic 1 reminds me a lot of Mega Man 1 compared to Mega Man 2, from someone who has already beaten Sonic 2. But probably better and a little grander than Mega Man 1. Like how Mega Man 1 has only 6 Robot Masters, Sonic 1 has less Zones than most Sonic games. It’s obviously not as refined as Sonic 2 also. The music is pretty good for it being the first game. Just a fun little game to kill a night/weekend on, but nothing mind blowing.
