I was pretty disappointed with this. I had really hoped for a shinier, prettier Wii Tennis and got... well, a basic collection of mini games grouped around thirteen old Sega games with no real logic as to why or where they were connected. The tennis element comes through each "group" being finished by completing a small tennis tournament.
You CAN just about play with the Wii mote by moving it but you can tell it's been designed for other consoles as by far the easiest way to play is to turn your Wii mote on it's side and button smash (like the buttonsmashing girl I am).
I'd only recommend this if you still hold a candle to console games of yore and until they add a Monkey Island minigame it's not going to do much for me.

I agree, it's very disappointing on Wii. I bought it a few weeks ago but have only played it a couple of times since. I was expecting a fleshed-out version of Wii Sports Tennis and instead it's more of a toned-down one...
Some of the minigames are fun though, like the House of the Dead one where you smash zombies with tennis balls!
