The gameplay refinements make this game much better, but the story is still terrible and short.
User Rating: 8.5 | Sonic Riders: Zero Gravity WII
Sonic is back and riding again, but with a new power. It goes like this....Apparently a meteor hit Earth and caused a bunch of robots to go crazy. Sonic and pals find this weird stone thingy, and the robots go after them. They learn it can alter gravity, and use that to their advantage. After meeting up with the long-lost Babylon Rogues, Jet explains its the Ark of the Cosmos (yeah, I was confused, too) and he needs them for some reason. Then Sonic teams up with Jet in the end to fight Master Core: ABIS (pretty much a remade Babylon Guardian). In the end, all YOU end up learning is the Babylonians from ancient times were aliens, Jet decides to stay on Earth (leaves many questions unanswered), and is open for another obvious cliffhanger. It's a pretty dumb story, but the gameplay makes up for it. Thank god you don't have to worry about the air meter anymore. Now you have a gravity meter, and it doesn't matter if it runs out, you won't be on foot. The zero gravity controls are very good, but the real controls aren't. Luckily, the wiimote on side technique lets you use the control pad, so don't worry about practically tilting the wiimote upside down. Sadly, there's still not enough characters. Silver and Blaze are awesome, and I was super-happy to see Amigo and Billy Hatcher, but in all, this game just needed a better storyline, more characters, and more stages. The missions were way easier than the first one and I unlocked the Chaos Emerald gear so fast it's not even funny (and frankly Super Sonic sucks in this game a lot because he's only power-type. I'm also getting tired of the remade stages that don't really differ between stories. The other big opportunity SEGA missed was using the Wi-Fi on Wii for online racing, but just like the Olympic Games, you can only check rankings as well as your own. We'll have to wait to see is it hits the so-called sequel to this game...
All in all, zero gravity is a good game with a terrible story. Hopefully the cliffhanger is true and there is another sequel with all the stuff zero gravity didn't have. I recommend this game for any Sonic fan of course, but I wouldn't exactly recommend this as a buy for non-Sonic fans. Rent it of play it at a friends. Maybe you'll be as addicted as I was. All in all, let's see when Sonic Riders 3 comes out....
