Well a year back I had these two fanmade concepts. One was a rather simple concepts centered around the player's dreams. It had two kinds of stages, those in the real-world and those in player's sleep. The dream level varied from dream to nightmare. The dream levels are unpredictable unlike the reality ones and each level has a nightmare gauge which is directly proportional to the time spent on the level. For e.g. if you are taking really long, the nightmare gauge will fill up and make the enemies stronger. There is alot more to it, but this concept is kinda flawed so I am not too fond of it.

I like the second concept more because it is a bit broader. It is centered around temperature. The worlds are planets divided into the north and south poles - the 'cooler' levels being the top half and the 'warmer' levels being the bottom half. The cooler levels are done first in every world - the goal is to find the 'core' of the planet to get underground to the warmer levels. For example - the cooler level would be a glacier and the warmer level is a water one (melted ice y'know). To get from the glacier to the water, the player needs to search for the water in the glacier (by, for example, breaking a floor of ice and swimming down to the entrance of the water level)

These concepts were not for a Sonic game specifically. It was just a game concept. That means it could apply to other franchises like Mario, Zelda and Crash.
