Get Daigasso! Band Brothers (I own it, it kicks all kinds of ass), get Osu! Tatake! Ouendan (I don't own it, but I've heard that it kicks all kinds of ass), and if you don't have New Super Mario Bros. yet, I ordered the JP version so I could switch my gray case with the yellow one, and I'm selling it for $28 (under US and JP retail) shipped on my list, if you're interested.
