I distinctly remember going to buy this at the local Walmart in 2009 along with a copy of Sonic Unleashed on the ps2. The woman at checkout scanned the ps2 game and even offered a warranty on the disk.
Unfortunately, she forgot to scan Mario & Sonic at the Olympic Winter Games.

It was just OK even for a free game. Not fun enough to potentially lose a job over.

The figure skating portion was pretty fun though.
