I always liked Super Mario World's. [...] with SMW you had this one big map and they were all connected. [...] And the way everything connected made it look like a cohesive world. Most Mario games each area just looks like some floating rectangle of land.
That's what I liked most about SMW's map. The progression of the stages felt logical-- you could see that the next area will be a cave, or over the bridge will be a forest. I suppose it creates a sense of scale. NSMBWii didn't have that. The only logical bridge between two worlds was climbing up the mountain of World 6 to reach the cloudscape of World 7. I don't understand how one could go from grassland to desert to snowland to tropical beach in a seamless fashion.
