(number of the beast hype)
Battle Royale would be an ok title for a new smash game. Nothing spectacular.
I don't really believe that datamine though.
The only problem I see with using the Royale or Battle Royale subtitle is that it
could draw connections to the Playstation Allstars: Battle Royale game, which Nintendo probably would not want to do.
In regards to the believability of the "datamine," well, it certainly comes across as a
very comprehensive list, which seems kinda unlikely. The subtitles for pretty much all of the games sound pretty iffy, plus a game that is that far away probably would not have a set title yet either, there would be worshipping, focus groups and then it may change based on the finished product. The largest sticking point for me, aside from the NintendoLife article link someone mentioned, is the subtitles for the four Pokémon games. The new entries sound
way too harsh for a Pokémon game, and immediately draw to mind Uranium, which people have mentioned.
