Research Poll - What game would you sign up for at an event?

[Zolom]

I am writing a research paper on my own time. The contents and subject of the research will not be disclosed at this time to avoid corrupting the quality of the research. Additionally, votes will not be displayed publicly, though after 3 weeks the results will be posted here for no reason other than ones personal interest. A lot of my free time will go into this research and your participation matters a great deal to me.

Based on your opinions alone, for whatever reason they may be, if you could only register for one Smash title at, say, the largest tournament of all time, what game would you register for? Alternatively, if you are not registering to play, if you could only watch one of the Smash titles, which would it be?

Thanks!
