Late last week I played through the first level of Sonic's cross-generational platformer on Xbox 360 -- a "reimagining" of Sonic's Green Hill Zone -- using both old (chubby) and new (skinny) Sonic. Here's how the pairing works: each level of Sonic Generations is playable with either character, and both offer different routes and perspectives. Before I got my hands on the game, a Sega rep walked me through the first level's various winks and nods to the original Sonic the Hedgehog: badniks, multiple paths through each level, and a particular mid-air ring-grabbing moment were immediately set up to invoke nostalgia. And though the level was rife with nostalgic touches, the rep confirmed that "you're not actually going to be playing old levels verbatim."
The first (and only) level I saw was the Green Hill Zone, but it was split in two by the two generations of Sonic -- now does that name make more sense? Chubby/Classic Sonic explored the level strictly from a 2D plane with a focus on platforming, in line with the goal of classic Sonic titles. It seems that the extra pudge is making it a bit harder for Classic Sonic to get his feet off the ground, though, as jumping felt a bit too sticky for a game so focused on platforming.
Skinny/Contemporary Sonic, meanwhile, borrows his style from more recent games like Sonic Colors, focusing instead on speed and style -- thankfully, we didn't hear him say a word. Not yet, at least. The story conceit of Generations is that Sonic's friends have been pulled into "time holes," thus providing the tenuous (and unnecessary) justification for revisiting the older stages. It also means that Generations will explore specific eras of Sonic history. Green Hill Zone represents the Sega Genesis era, while other areas will represent the Dreamcast era and the "modern" era. It also means that we're at a high risk of encountering Sonic's friends.
While Sonic's older iteration stuck with a fixed 2D camera, the younger version is more brazen, switching from third-person to 2D and exploring many in-betweens along the way (controlled by the game and not the player, notably).
Both versions featured something I'd never seen before in any Sonic title -- the ability to move into deeper planes. Sticking to the three-path formula of past games, this meant that the verticality of parts of levels was supplanted by depth in and out of the 2D plane, a bit like LittleBigPlanet. Before purists freak out: no, you cannot switch between planes whenever you'd like. Much like switching between different paths in a level, depth switching is handled at various intervals -- a hidden spring that pushes you in the right direction, for instance.
Sonic Team's Takashi Iizuka is heading up the producer responsibilities, and fans will be happy to hear that this game has been given some extra time in the oven. Is Generations the game Sonic fans have been waiting for? Well, let's not go there just yet, and rather leave the last word to Sega's community manager: "It's for the old fans, it's for the new fans. It's kind of for every Sonic fan. And if you're not a fan of Sonic, this is why you should be."
