We got Deca Sports and Game Party since the wife started having monthly wii parties
For our own games we both LOVE the lego games - Batman, Indiana, Star Wars! I still have Mario Galaxy, but never even put it in yet..lol
We like the deca sports and game party games because they were cheap and some are up to the 4 players we were looking for also
Oh and Mario Super Sluggers SUX - I am glad I had a free rental coupon for blockbuster so I didnt waste any money on that piece of crap!
I myself am looking to find a good 4 player tennis or baseball game that you actually use the controller as a bat, etc. I hate those games that you push a button and flick your wrist to swing a bat or whatever! I am all for using the wiimote as the device for sports games, not as a dumb controller! Now Lego has a NICE control feature, expecially with Batman, since you use the wiimote to move the batarang target around.
people still see mto like the Wii Sports game...go figure.
