Well I went with the 3DS Generations, so I'll go with the DS Colors I think.
The 3DS version of Generations is an abomination and can not be compared or associated with the console version.
Anyone who hasn't played the real versions of Unleashed, Colours and Generations has no right to comment on the current state of Sonic games.
I haven't played SA2, but I bet it's just as bad too.
Night and day, sir. I suggest you too actually play games before commenting on them.
