I remember spending countless hours playing 2P in Sonic 2 with my brother and other friends. Often so much that I would become used to seeing a ovoid jumping Sonic and Tails and when going back to the main game seeing everything as obscenely large in comparison. Emerald Hill, Mystic Cave (my brother's worst nightmare), and Casino Night were a great balance between one another, despite having identical layouts to the 1P version of the zones. I think if they included one more, Metropolis would have made an exciting candidate. Sure there were only 3 zones and Special Stages...but as minimal as they were, I've always felt they were more wholesome compared to those in Sonic 3. Sure, Sonic 3 had exclusive levels and power-ups, but I didn't appreciate the whole "lap" method. For me it was a great disappointment despite the wonderful music and strange power-ups/items. One thing in particular, you can't glide as Knuckles, you only have Sonic's (invisible but audible) insta-shield. I can probably count using my two hands how many times I've actually played through Sonic 3's 2P mode...I found it that boring and frustrating. Most of the time I would play it by myself, just I could listen to the music when I was younger. I was only amused by how graphically different the levels were in comparison to the actual zones in the game. Sure, they had their one gimmick each, but each area felt rather bland, leaving the whole thing feel tacked on as an afterthought. Although partially touched within other topics, I feel we've yet to have an in-depth discussion regarding these differences. What are your thoughts?
