Most disapointing playables

[Sho_"Rocker"_Daisuke]

Sonic the Hedgehog - SONIC the Hedgehog (2006)

being a Sonic fan, I found that in this game, he moved too slow for being "the fastest thing alive" in this game, also a whole bunch of moves were quite glitchy, like the homing attack and such

Another sad thing is that Knuckles moves just as fast as Sonic does in Sonic Adventure, or at least DX.

Big the Cat was disappointing.

I never really noticed that about Knukles, mainly because his levels really weren't much of running around getting to a checkpoint, they were more treasure hunting games

I think they just put Big in there to make it that you have 7 playable characters by the end (including Super Sonic), and his game play was different, not so much dissapointing, he was a dissapointment in Heroes though
