Apart from the fact that the A.I. can be annoying, this is a decent game with lots of fun mini games in.
GRAPHICS- The graphics have a nice cel-shaded affect which makes it look cartoony giving Sonic Shuffle a nice touch to it, theres not really much else to be said about the graphics apart from the way they move. It's not really got any polygons which is good too.
GAMEPLAY- The most important part in my opinion, (I won't go to far into the storyline because of spoilers) but it sets you about like Mario party on what looks like a board game but with cards instead of dice. The mini games are very fun IMO with only 5 or 6 I don't like. If you have at least 2 friends to play with on this it can be a great laugh too. The thing that can get annoying though is (unless you go on easy) the frustration of the difficulty, you'll be so close to getting to the precious pearl (things you have to collect) and then the boss either uses his best attack (on you) or the COM stops you from getting there. Apart from that the gameplay is great and addictive.
SOUND- I like the sound, it seems to fit with the enviroment and it's not annoying or boring, it fits right with whats going on and I find the tune can get stuck in my head for a day or two. Overall, good sound.
VALUE- I definetly think this game is worth the money and reccomend this for a fun party game. If you a Sonic fan (like myself) then buy this, if your not familiar with Sonic or don't like Sonic games, then get Mario party.
