I like how they made a remark for the Wii, and when we played the original, the original one is by far the hard that the Wii one! I know, I kind sucked at first, but got better while practicing with my bro in the multiplayer match in the Wii one! XD
I find the hardest part not figuring out the patterns, but timing the attacks right. Also, I've never played the Wii or SNES version, but I've heard they're just as hard as the original.
Yeah, my brother is stuck on Mr. Dream, and after you beat him you have to face everyone again, in a stronger form, because you became the champion, but if you lose one match you lose you title, it's so freaking frustrating for him! :(
