I wish I could only play the game as classic sonic. The gameplay as classic sonic is fun and the levels are beautiful. I just can't get myself to enjoy the levels as modern sonic. I find modern sonic a bit awkward. I also wish SEGA would almost eliminate the stories in these games and have the story implied like it used to be in the originals. I'm playing the game for the gameplay. If I wanted a story I'd go read a book. If the story was removed, it would force SEGA to make the gameplay awesome otherwise the game won't sell.
I will be honest, I am a total Sonic fan, but I am not one of the whiny fans who complain about how nothing is like the classic games from the 90s. I enjoy almost everything from 1991 to the present, and I have to say this is quite a fantastic mix of modern and classic gameplay. Thanks to a time based incident created by Dr. Eggman both in the past and present, a place outside of time know as white space contains destroyed parts of time and now sonic of the past and sonic of the present must work together to restore time and stop Dr. Eggman, and all on sonic's current birthday. The console version contains levels known very well by fans from across the franchise's 20 year history, remixed to accommodate the gameplay of the genesis games and the recent gameplay inspired by the daytime levels of Sonic Unleashes, which involves alot of jumping and boosting. If you're a sonic fan, this is definitely a buy, if you're into fast paced action games this is still worth trying. I highly recommend it.
The game wouldn't even go past the first level so wasn't able to play it to give more info on the subject only that I received it 11/18/13 & sent right back the next day 11/19/13 since it can't be played there's really no since in keeping it is there? I only noticed one small scratch & I tried cleaning but it still made no difference in the end!
