PopCap Arcade Vol. 2 includes three games for $20

They said the same thing for Bejeweled a few years back - but apparently it only hit really hard with at-home mothers.

...Peggle hasn't reached everyone yet - surprisingly enough.

I am pretty sure Tetris is this generation's Tetris. There have been at least 3 Tetris games released on the 360 alone, I know of at least 3 flavors for my current cell phone, and I am pretty sure it's gotten at least one release on every other console out there right now. Peggle on the other hand is on one handheld, one console, cell phones, and PC/Mac... if we're still playing Peggle in 20 years (at which point we'll undoubtedly still be playing Tetris), yeah, we can make Tetris comparisons :)
