The footage of modern Sonic Green Hill Zone from the pre-E3 event really reminds me of how intensely I love the Colours gameplay. I really hope they can sort some way to have that co-exist with classic Sonic stuff in the future, because I'd be really bummed if the vocal backlash of notorious classic fans somehow invalidates the appeal of the new ones.
I like both, I really do, but that's just it; I like both. That's genuinely scary because the way 3D Sonics have been shunned - by people burned by the wonkier ones, by people who honestly don't know how to play them or even people who never bothered trying - Generations is inevitably gonna prompt loads of reviewers talking up the classic stuff based on familiarity if nothing else. Familiarity always wins. It didn't matter how good Street Fighter 3 was, it was never gonna stand a chance against the nostalgia tour de force and pick-up prowess of SF4. Sure, returning to roots, re-evaluating what something is essentially about is healthy and can ultimately be revelatory. Mortal Kombat is an especially apt example of this, and Sonic - especially in regards to 06 - sorely needed it thematically and in terms of its imagery.
But the new thing in Sonic's case - and in the case of plenty of action/adventure games gone 3D - is such a vastly different thing from the old thing, and one with its own set of genuinely rewarding mechanics. It's an adrenaline filled, twitchy F-Zero to the methodical and subtle Wipeout of the old ones, and I would be profoundly saddened if the result of Generations is a Sega without faith in the mechanics they've finally, after years of banging their collective head against a brick wall, have arrived at.
As an aside; the irony isn't lost on anyone, surely, but I took Sonic 4 for a whirl again today (having finished it up proper back when it came out) and what an amazingly bizarre thing that's turned out to be. That really was the one that should've been the new classic Sonic line of games. Now, frankly, it's just this shitty, bland thing inbetween *every enjoyable iteration of Sonic* that isn't evocative of any of them, let alone an appealing thing of its own.
