Today I'm playing a game that I've never played before, even though it was beloved by a lot of my classmates in the mid-90's. I was a Nintendo guy across the board until around 1997 when the Playstation got Final Fantasy VII.
This is an interesting game. Sega wasn't able to get Sonic 3 done by the intended release date, so they ended up splitting it into two different games. One was Sonic 3, while the other was released later in the same year as Sonic and Knuckles. Via plugging the carts into each other, players could play the full combined game that was originally intended to be Sonic 3. That's a good thing, because individually the two halves aren't all that impressive as full games. I liked Sonic 2 more, and a lot of that is probably due to it feeling more like a finished product.
