Sega Announces new 2D Sonic title

[Vipershark]

Secret Rings is decent at best.
It relies on an rpg-like level up system which makes sonic run faster and handle better as you level up.
Only problem is, until you get him moving fast, the game is almost unbearably slow.
Once he speeds up, there are certain areas where the game genuinely feels fun. But they're short-lived, as the game goes right back to being an annoying mess.
The controls are awful, and there are cheap deaths galore.
At least you get unlimited lives.

I've never played Black Knight, but I've heard it's better than Secret Rings.

As for Unleashed, the 360 version is pretty fun.
While there are definitely waaaaaaaaaaaay too many werehog stages (which are all really long and repetitive, but not exactly bad) the speed stages where you play as sonic are pretty fun. There are some annoying segments, but overall, the game isn't bad. And the music is pretty good too. I especially like the Night Mini Boss music.

As for the Wii/PS2 version, my brother has that and he says it's terrible.
