There have been quite a few, although they seem to be more indie now. Divekick and Skullgirls are the two I've heard the most about, for example. Still, the genre is definitely past its heyday.

On a very realistic one. It's not lighting the charts on fire anywhere: even in its strongest territory, Japan, it's slowing down noticeably, and the system has far less traction in the West than its predecesor. A fair grade for the system would be "Needs Improvement." I suspect the fact that it has fewer big titles, and that more of its heavier hitters are largely concentrated in a smaller number of genres (most notably JRPGs) plays a role, although the system's other drawbacks have been extensively documented on this site already.

It doesn't NEED anything. It's already a selling crazy amounts of units per week and it would continue to do so even without the help of Smash Bros. I still stand by my opinion that this is a stupid move by Nintendo.

No, but Tomodachi Life might do the trick.

Nintendo can give a few copies to prominent YouTubers and call it a day. Tomodachi has that kind of viral potential.

To be honest the 3DS version is playing second fiddle to the Wii U - my hype is not nearly as large for it, in comparison. It will be an appetizer until the main course arrives in nov/dec

The 3DS version will sell well - likely to sell a fair few console - but I have a feeling the Wii U is going to eclipse it in every way - in system selling ability, Lifetime sales and of course quality
