I only played Mario Party 5, I thought it was fun.
That being said, Wario Ware Mega MicroGames is one of the biggest insepid pieces of shit I have ever played. I ordered it (GAF recommendations lolz)thinking it would be alot of fun for a few of my non-gamer friends to try out. They looked at me like I was distinguished mentally-challenged for buying it, and asked for me to put Donkey Konga back on.
