this version is weak in my opinion
design; the cutscene are the same as the HD counterpart, but the hub world in the Wii/PS2 version looks like a menu style selection. the level design are average since its a wii game. some levels are not there since HD counterpart has more levels then the wii version.
gameplay: the gameplay is kinda similar of the HD but Sonic's top speed and Sonic Boost gauge can't be leveled up permanently and are determined by rings gathered in the stage on the Wii/PS2 version. If Sonic takes damage, he levels down by one bar of boost, there also an action Chains that are a feature found only in the this versions. When Sonic strings together certain types of combos, he can create an Action Chain. The more moves Sonic does, the more Boost power he gets.the werehog stages are not long as the HD version but is still fun to play, sure they not have combos like the HD version but still great.
overall: the game is too easy for me since im used of the ps3/360 version but overall this version is okay not the greatest but still okay, but i rather play the ps/360 version cause is much better
