Nintendo can legally shut down any tournament featuring its games
Nintendo has been getting aggressive on controlling the public use of its games, although it quickly doubled back on the decision to stop the Super Smash Bros. stream at EVO 2013. This article does a great job of explaining how all this can happen, why games are different than movies, and all the other legal details of these situations.
Any company can exert this control, of course, but most see streaming as great publicity; many people in PR now actively court Youtube personalities to create videos and playthroughs of their games. While Nintendo may be in the right when it comes to this stuff, at least legally, it may not be the best way for the company to play its hand from a purely business perspective.
