I played it at Gamescom. I am by no means a mega Sonic fan, the last one I played was Sonic Heroes. I actually thought it was a good deal fun. But to be fair, I generally like large moody empty open worlds. The virtual levels that feel more traditional 3D Sonic offer a really nice change of pace. As to the pop in, I noticed it once but it otherwise didn't distract me. I would have to see it again, but I bet the motion blur they put on Sonic's full speed mode disguises it.
Felt like there was a ton small sections to gather rings or character upgrades around every corner, and I think I would have been compelled to stop for even more than I did if the demo wasn't timed. They also have fighting game training-level esque tutorials where they show you some of the moves Sonic can do, and it feels like this is going to be fairly deep mechanically. Whether the difficulty will require it or not, who knows.
