Every competitive fps game i played on the wii was lackluster and part of the problem imo were the controls, so I think i would feel the opposite. If there were more motion control shooters I would be worried but even then, Nintendo's poor commitment to online multiplayer makes me avoid these experiences on nintendo platforms altogether.
