Sonic 2 is the first Sonic game I've ever played and my favorite Sonic game but it certainly isn't perfect. Some of the zones (like Metropolis) are just a pain to go through and I often find myself just giving up once I get to oil ocean.
I like this game but it has so many issues. Half of the zones are just really bad, the only thing that keeps making me go back to this game is Sonic. He's just really fun to control.
I like Sonic 1 but oh my god it is not a good game. This port makes it actually playable. Sonic 2 however, is really good and now it's in widescreen and on PC. That's enough for me to recommend this to anyone.
