Did Konami copy EA by doing Pro Evolution Soccer? You can't 'copy' something so general as doing a sports game or a set of mini game... I don't think either Microsoft or Sony copied Nintendo by doing an Archery or gladiator game... In fact... Wii sports only has boxing as a fighting game... it's a generic wiggle your fists game. The gladiator(from what I've seen in the demo) game gives you the ability to use shields and swords and fight a real sword fight.
I am a Gamer... I play games and not consoles. I have a PC and Console on which I game... I like games. End of Story!
