The debate about ARMS amongst Nintendo fans is lit due to its launch beeing only 2 months away. Many think the game will pull off another Splatoon while others think it'll perform poorly due to beeing a Fighting game. In my opinion the success of Splatoon was caused by two major factors:
-The Global Testfire that created an enormous ammount of hype for the title by letting players try out the game;
-Nintendo's choice of heavily advertising the game, putting behind it an advertisement budget equal to that of Mario Kart 8 ;
I think that if this two points were to be applied to ARMS the game would definitely become a multi milion seller but in reality we don't know what Nintendo plans to do: there's certainly still time to make a Demo given that the Global Testfire took place only a few weeks before the launch of the game while on the Advertisement part it really depends on wether Nintendo thinks the game is worth it AND if they're capable of doing it, in fact ARMS is releasing only one month and a half after Mario Kart 8 Deluxe and one month before Splatoon 2, the new iterations of the two most heavily advertised games on Wii U.
How do you think Nintendo will handle the ARMS advertisement ? Will we see a Demo announced before release ?
