An article that was written on The Sonic Stadium mentioned a deeper meaning to the theme song written for Sonic from the game Sonic Adventure. The stated idea was that SEGA would continue as they had previously and would not change based on the ideas of others. Through the years SEGA has created several different systems and technologies. From arcade machines to a personal computer. Each time they have developed their own system, usually with the most advanced technology. SEGA's systems were usually ahead of their competitors (a technique which Nintendo is now attempting to use). But now that SEGA no longer makes systems and instead Sonic Team creates games for many different companies, have they stayed true to form?
In Sonic Adventure, Sonic's levels stayed true to form as did those where one played as Tails or Amy. Yet certain other aspects of the game were wholly new. For some it was a welcome difference. For others it wasn't what Sonic games were about to them. Now a new game is coming out. Shadow the Hedgehog, a game that contains the central points of speeding hedgehogs from Sonic Team, yet has a wholly different attitude and goal about the game. Some would say that all things change, this is true. Some would say that the games now are better than before while others would disagree. With this idea in mind, let's take a look through a comparison of changes that have occurred through the years.
