Once again the "big three" are hanging tough in the top 3 spots and showing no signs of slowing down. It makes us wonder what game might finally break into the top 3 over the coming weeks and break up the dominance these three titles have had on the Top 20 over the past weeks.

The biggest climber this week would have to be Fun! Fun! Minigolf which went from not even making last week's chart to jumping all the way up to the #6 spot. Not far behind it is Tiki Towers, another release from last week which climbed up to the #7 spot.

The biggest dropper this week was Space Invaders Get Even which fell a whopping 10 spots down to #18. Strong Bad Episode 5 - 8bit Is Enough also fell 9 spots to #20 which could signal the end of the Strong Bad series on the Top 20.

This week also saw My Pokemon Ranch make a surprise jump up to #9 after a slow descent on the charts over the past few weeks. It would seem that the Christmas holidays were kind to the game.

We'd also like to take a moment to thank everyone for making WiiWare World's first year a success. It's been a great year and we look forward to an even better 2009.

Happy New Year from the WWW team!
