Gamertell as posted a very positive review of the Xbox Live port of PopCap Games' Peggle.
From the review:
"PopCap Games is well known for its array of easy-to-play casual games. It's games are distributed on just about every platform including PC, cellphones, DS, PSN and Xbox Live. Of all of PopCap's games one of the most popular titles has to be Peggle.
Peggle takes a simple idea of removing orange colored pegs and makes it increasingly addictive as time goes on. Available on Xbox Live for 800 MS points, Peggle is easily one of the most enjoyable experiences you will have regardless of whether you call yourself a casual or hardcore gamer."
