I have enjoyed Sonic 4 a lot. Sure it's not perfect, but that's what we have the Mega Drive games for.

I think it's garbage. It plays like a by-the-numbers, pandering, "Sonic fans like this stuff, right?" sequel with atrocious physics. So, nope, can't say I've gotten my money's worth on this one. Sorry, Sega!

I was torn by Sonic 4 at first. I know the physics are completely different to the original games, and yes it's really just a HD remake of Sonic's best 16-bit moments, but I ended up falling in love with it anyway. The level design was better than I'd expected, with comparatively fewer pits of death than I remember and all the bits I love best about Sonic.

I'm not going to say it's his best ever outing - it's got nothing on Sonic CD - but it's a really solid start and I think the follow-up could be ace.

I've enjoyed Sonic 4 about as much as the first few games on the Megadrive, which is good fun for a few hours but soon loose interest.. it's good but about 10 years too late to be honest.

I thought that the demo was okay but something about it just felt kind of off to me. I can't bring myself to spend the 1200 points for it especially considering that the game so short and episodic. However, as soon as it goes on sale I will be sure to give it a download. I just hope that Sega is actually listening to the criticism of the fans in order to make episode 2 more polished sequel.

I have it on PSN (boo, hiss), and I love it.  I wish they had kept the old physics (at least for rolling), but once you get used to them it's fine.  I only need the trophy where you beat the boss without getting hurt at all to complete it.

I would sell my soul to see Sonic CD on VC or PSN (or I guess I could just track down that GCN compilation with it on there - but then I wouldn't have that awesome icon on my Wii menu for all to see).
