The big buzz in the world of Sonic is their impending new game, Sonic Generations. Sonic has had an incredibly rough life in the past decade, and even though the handheld games were pretty game, the console games were still met with pretty mediocre reception (though Sonic Colors was pretty decent). Generations is set to FINALLY change all that by appealing to old and new fans by featuring a classic Sonic and a modern Sonic. I don't want to spend too much time explaining, so you can look up all the info yourself.
What I want to talk about is the recent demo they released (like literally just released, I just downloaded it off the PSN) to coincide with Sonic's 20th anniversary. Its just one Green Hill Zone level, but I just finished playing it and I gotta say...I'm pretty impressed! I'm tempted to say they finally got it right this time! The graphics are nice and vivid, Sonic and his movements look great, and the platforming feels just right. You really feel the speed, and is infinitely more satisfying than what we got from Sonic 4.
You see, I'm one of those people that thought Sonic 4 was very unsatisfactory and wasn't enough to fill that void Sonic fans have looking to fill. The graphics look half-assed and stale, and Sonic's movements were stiff and awkward, thus making the platforming a bit underwhelming. Then after Sonic 4's less than enthusiastic reception, some fan on youtube released videos of a Sonic game that seemed to do what the entire Sonic team couldn't do. The graphics were several times more vivid and nicely blended, and Sonic's movements were much more fluid. Fans cried out "why can't they make a game like this?!". But with this new demo, I really think they've created something quite close to those fan videos.
But don't take my word for it, go play it yourself or check out this video of the demo in its entirety. It is quite short, but oh so sweet. Can't wait til this comes out.
