Depends on your choice.
At sonic unleashed WII/PS2 version is sonic colours surely better.
At sonic unleashed XBOX360/PS3 version it depends on what you like, the most will like sonic colours more where it's more based on speed. At sonic unleashed you have a lot of werehog stages which are slowly and in my opinion very good, but doesn't fit in a sonic game.
This is just an opinion of me, maybe you think different about it so to find that out you can watch some gameplay movies on YouTube. ;)
yes
unleashed
Sonic Colors
They are both great games, but i'd say sonic colors
Sonic and the black knight that game is so much cooler than Sonic Unleashed. I mean is Knuckles in Sonic Unleashed? No. Is Shadow in Sonic Unleashed?No. Plus there playable too on Sonic and the black knight.And is Sonic Unleashed multiplayer?.N-O. But Sonic and the black Knight.
This question is opinionatic. Which do you think is better?
No, it is the direct sequel to Sonic the Hedgehog 3 released in 1993.
There will be 2 options: Play as the original Sonic in the original levels, or play as the newer Sonic in levels like in Sonic Colors or Sonic Unleashed.
People refer to Sonic the Hedgehog 2006 to be the worst Sonic video game ever, whereas they do not say that about Sonic Unleashed. It is only up to you to judge though.
Sonic Colors.
Sonic Unleashed is 7+
Sonic Unleashed happened in 360.
