I bought the CE, and the Strategy Guide definitely came in handy a few times. The bonus chapter was reasonably long and enjoyable.
This is the first time I've really enjoyed the FROGs, but there's lots of other fun stuff to do, too. The mini-games were repetitious, though, and since I couldn't figure out how to solve most of them, I skipped them quite a bit.
Even so, the game length was excellent.
The Hint and Skip buttons charge quickly at the Casual level. No penatly for clicking! I love that.
Graphics are nice and bright, and the music did not become annoying.
All-in-all, I was totally satisfied with the CE version of this game.
