Compared to the first gameplay video from a few weeks ago, does this video look ... smoother? Either Sega is trying to make their dashing hedgehog look marginally better, or we're imagining things. At least this title is still staying true to its 2D roots. We wouldn't want our Sonic any other way -- too bad the gameplay still looks identical to the previous Sonic Rivals in every way.

No, you're not looking at footage of the original Sonic Rivals. This is the sequel -- and it looks exactly like its predecessor. Distressingly, the framerate of this video is choppy, and the gameplay seems even more barren than before. Maybe it was too early to show this, but our confidence in Sonic Rivals 2 has taken a huge hit.

A leaked retail release calendar accidentally revealed Sonic Rivals 2 a little too early. However, Sega has officially announced the title today. This PSP-exclusive sequel will feature a revamped rival "jostling" gameplay system for tighter head-to-head competition. (One of the problems of the first title was how limited conflicts were between the racers.) A brand new Battle mode allows two players to jump into six different multiplayer challenges. With Game Sharing, players will be able to partake in the challenges with just one UMD. Power-ups have been improved for the sequel, giving gamers a fairer chance at competing.

In addition, Miles "Tails" Prower and other new characters have been added to the playable roster. A new single-player Free play mode will allow characters to explore each level at their own pace. Just as before, each character in the game will also have their own unique signature moves.

Finally, card collection returns in Sonic Rivals 2: it now features more than 150 collectable cards, which will enable players to customize characters with new track suits, unlock PSP backgrounds, and unlock Cup Circuits. Sonic Rivals 2 is currently scheduled for a Fall release. Check out the first images of the game in our new gallery.

The keen eyes at The Sonic Stadium have noticed mention of Sonic Rivals 2 on various websites. Considering how the first was exclusive to PSP, we shouldn't be afraid to think that the sequel will also be heading to the handheld. Game Informer Online features a mysterious listing and a leaked retail release calendar shows the title releasing some time in November.

The first game wasn't too shabby -- although the execution was weak at times, the concept of turning Sonic into a racer was novel. Rivals, at the very least, included some fast and pretty visuals (albeit a sluggish framerate). Let's hope this potential sequel fixes the issues found in the first game.
