The answer is in the hope that one day Sega may once again produce a Sonic title that even if not as good as the old 2d games, is at least as good as Sonic Adventure on the Dreamcast.
But surprise, surprise Sega has missed the mark yet again. While this is certainly better than the horror that was the last 360 game, it still misses the point of what a Sonic game should be, chiefly seriously fast and reasonably challenging. The sonic levels are great. So fast they will make your eyes bleed, and get this, at times the camera shifts so that it feels like you are playing one of the old megadrive games. The levels are also pretty long, and well worth replaying to find hidden goodies.
So why only two stars? The problem is the rest of the game. Unfortunately you cannot just select levels you want to play from a menu like in the old days. Instead, they are held together by what is essentially a very feeble RPG style game world, with more levels becoming available as you progress through the story. But Oblivion this is not! This usually means clunking around talking to every single annoying character until you find the right one to tell you something so that you can progress. This became tedious after about five minutes, especially with annoying controls and camera angles in these areas. The voice acting and cut scenes are also pretty naff and child like, and they begin to grate immediately, especially Sonic's new sidekick, who resembles a flying pink squirrel and acts and sounds like a hyperactive four year old. And i used to think Tails was annoying.
The biggest let down though, are the Werehog levels. They just seem so out of place in a Sonic game. For every lightning fast Sonic level you play and enjoy, you know it is to be followed by a lumbering and slow Werehog level, which become so repetative and boring it is untrue. One level took me over 45 mins to finish. Hardly the lightning quick pace you expect from a Sonic game! For some reason when Sonic becomes the Werehog, his ability to run goes out of the window, and is instead replaced with to ability to beat things up. While this sounds fun at first it soon becomes very repetative beating up hoards of uninspired generic enemies that take ages to die, when regular Sonic can down the same enemies with one hit in his levels. Compared to the Sonic levels, the Werehog levels feel like you have bought a Ferrari that keeps stalling every 10 miles. The thing is, that if Sega had done all the levels as the blisteringly fast Sonic levels then the lame RPG bits could have been forgiven. So why on earth didn't they!!! Fans of Sonic want fast and furious action packed stages. For those who want to explore and complete quests there is always Mario. And let's face it, Nintendo do this sort of game so much better.
Next time Sega, lose the Werehog and the rubbish RPG, and just stick 30 or so Sonic levels together. Story doesn't matter. The old games never had much of one and look how well they turned out.
Overall, kid's will probably enjoy it, but for me I think it's time Sonic and I parted ways as Sega has had far too many chances to get the franchise back on track. Another missed chance. Shame.
