From playing the games I would say a "zone" is roughly the size of a small country but what makes them unique is that the zones themselves have there own unique environments that works with or just next to differing zones despite complications or contradictions the zones would have on one another. There are only a few capable navigating through these zones such as Sonic, his friends or vehicals made for the situation.
Zones may also not follows the laws of physics or nature being that either that they can vary to geographically impossible sizes in yet still retain it's nature. Almost all the zone can still have identifying features which makes them reconised as zones such as unique rock formations, such as loop-de-loops, cork-screws and even parts of it's earth that levitates against gravity without the need of supports.
An example are the zones Sandopolis Zone and Icecap Zone of Angel Island. These zones are of quite opposing environments, Sandopolis is an echidnan city (simular to Egyptian architect) and is also located on a vast expanding desert. Icecap is, as the name implies, the frozen top of a large mountain surrounded by freezing waters with glaciers and regular blizzards.
In yet these two zones along with many other zones of differenting biomes, exist on a floating island that is somewhere around the Stratosphere to Mesosphere. These environments cannot be possible at such altitudes (Maybe Icecap Zone can being high altitude is what makes is cold). Also, while Angel Island is the size of a continent than a small island, how can it have a large desert that goes beyond vision?
I am not a geographer so not entirely sure how it works but my guess is Angel Island is roughly the size of Australia. (This might have been in mind when it was decided Knuckles would be an Echidna which are native to New Guinea and Australia, despite Knuckles heritage being of an Aztec like culture.)
While there are urban zones like Spring Yard Zone and Star Light Zone, why humans (if humans) purposely make such zones I do not know. (what is the purpose of the roads of Skyscraper Scamper? They are impossible for use by any standard vehicals which can be seen in the stage.) It's possible Dr. Eggman makes his territory zone like purely for defence, he could also be the cause of various traps laid out around other zones, but who is behind the obsticals that give Sonic advantages like Springs is unknown, unless placed there for public use and not specifically for Sonic.
- Mystic, come on, you know this is more appropriate for a forum than a talk page. -- Supermorff 07:42, August 14, 2011 (UTC)
- I'm not sure. Maybe they're just not accessible/obvious enough. You used to be able to get to them from the sidebar (when the sidebar still existed) but now you have to be looking for them. -- Supermorff 18:19, August 18, 2011 (UTC)
