Ok, first lets start with the Pro's.
Amazing 3D graphics. Great customization. The multiplayer function is great, EZ to get coins, awesome tennis power hits.
Story mode, completed it in A DAY (I played the game 3 times, and I won 1st place.) Tournament mode, was completed in a day!!! Wayy too short. Sure you can replay, but the first time round, is supposed to take at least a week!!! In my opinion...
Also,the camera moving is SOOOO annoying. I can never get it to stay in one spot :(
Other than that, its pretty good. On a rating of 1-10, I give it a 7.5
Received and played this for ~2 hours last night, and was utterly bored by the end that I've already sent it back. You must be a tennis fanatic to enjoy this dumbed down tennis game (I will not call it a sim).
It is technically fine, as far I can see (smooth graphics etc), but just oh so forgettable.
Guess my 3DS is going back on its charger to rest for a while...
