DSiWare: Sudoku Master, 500 Nintendo Points
This Sudoku collection offers 150 puzzles to test your brain with, as well as several tutorials and a Title Mode that apparently lets you work your way up the Sudoku ranks. The puzzles were created by Nikoli Co., Ltd., and the game comes with tips from Sudoku master Maki Kaji.
WiiWare: Water Warfare, 800 Wii Points
This "first person squirter" puts a water pistol in your hand instead of a more conventional firearm. There are three map themes to choose from, creating a randomized map each time you play. You can play a two-player split-screen match locally, or with up to seven other players online.
WiiWare: Reel Fishing Challenge, 500 Wii Points
This fishing simulator promises excellent environments, with realistic-looking and -moving fish and a variety of lures. Try to catch specific kinds of fish in mission mode, or just kick back and relax with free play mode.
WiiWare: Silver Star Reversi, 500 Wii Points
If you remember Silver Star Chess, this is the same deal with a new game. Play against another human or against one of five computer opponents; you can save mid-match, review moves post-match and restart a match from any point during review.
Master System: Fantasy Zone II: the Tears of Opa-Opa, 500 Wii Points
The Nenon planet forces are once again attacking the planets of the Fantasy Zone, and Opa-Opa is once again responsible for saving the day. The gameplay seems the same as before, as the press release offers no gameplay details.
I’ve heard about Water Warfare, it seems like it could be pretty good. Also I need to play more Sudoku.
