After a month of owning my DSi, beating 4 games. Pokemon Black, and all three Layton games. I must say was kinda of let down with Pokemon, not sure why. The last pokemon game I played was Gold back on the colour. But this is not the point I am writing this blog, I write this because of Professor Layton, Playing the game has made me noticeably smarter (but there were some puzzles that really pissed me off) I cannot wait to play the next ones and this will be the reason I will pick up a 3DS (2nd gen and price drop =D)
Now I am playing The world ends with you. Kinda of like it but I since I was switching back and forth between this and two of the Layton games which affected my focus on the game story. I will beat it on day but not now, I am looking at picking up my next game. It is between Mario and Luigi Inside Bowsers Story (24.99), Picross 3D (19.99) and Rhythm Heaven (9.99 I think I saw this price at BB)

I looked at the QL of Picross 3D and I was so confused with the circle numbers and square numbers Jeff was talking about.
Since I play my DS on mute picking up Rhythm heaven might be a waste but it is really cheap to buy.
Mario and Luigi looks good but kinda of iffy on it.

What should I do? Also I do not want to pay more that 35$ for the game  (with taxes and CDN, might look at amazon if it is really cheap)
