Super Punch-Out!! once again puts you in the shoes of Little Mac (Which has finally been confirmed in today's press release - Nintendo previously never said who this boxer was!) as he fights through four increasingly difficult boxing circuits, taking on a total of 16 opponents on his quest to become the new number one. - It features almost exactly the same gameplay. Pretty much the only new features are a time trial mode to practice your strategies, and a power meter during battles - When this fills up, you can throw extra strong punches as long as you don't get hit.
If you need some more convincing you can of course read our Super Punch-Out!! review.
Strangely enough, there are no new C64 or Arcade games today. Get on the ball, Nintendo!
On WiiWare, you can grab just one new title as well - The only recently revealed Bonsai Barber by Zoonami. The studio head formerly worked as lead developer on GoldenEye 007 on the N64, so perhaps this will turn out to be a surprisingly good title?
