I guess it's understandable that some of them are tired of Smash 4, since for the longest time that was the only game they ever had playing. Personally though, I just don't understand why anyone would go through the trouble of carrying a big heavy TV and PS4 all the way out to a public place like the food court just for a game that only one person could play.
If people are playing it instead, then they must just be trying something new, I'd say.
