2 or 3 M isn't groundbreaking considering it'll come out near the launch of the system (hence having a longer lifespand than say Splatoon on Wii U which came only 3 years after the launch of the system) and the Switch seems to be selling far better than Wii U, meaning that it'd have a far smaller atach rate.

-eh, Nintendo games are a group of their own imho: us Nintendo fan  tend to trust Nintendo when they try doing something new because Nintendo is know for the quality of their games, hence expecting new thing to still be really good;

-same as the previous point;

-in the last couple of years there weren't that many fighting games in the first place, Skull Girls was Indie, Pokkén was on Wii U and was dropped like a rock by Bandai, SFV lacked basic content and was backlashed...

It seems extremely simplistic, but that could also attract that certain crowd-who-shall-not-be-named to pick it up. Honestly, its success hinges on how much Nintendo markets the game. Due to its simplicity the message is easy to get across and it looks quite fun within a 30 second viewing.

Nintendo has been on-point with marketing so far, so I'm hoping this continues throughout the Switch's life.

I played it and it plays like a hit.

it could do the 3 mil life time.
definitely can see 1.5 mil this year alone if Switch will continue this momentum.... and it was fair to release this before Splatoon 2. the other way around could have hurt Arms sales.

same like Splatoon (1 this will be out at the right moment and to satisfy appetite of Switch owners.

I don't get the excitement of this game. Looks really bad. Maybe fun for 10 minutes if you have a barrel of alcohol...

Don't hold them to it, your expectations might scare them out of their better work.

I see it selling on par with Pikmin games at best.

We'll have to wait and see, splatoon took many people by surprise, however I don't think ARMS will be as big as splatoon.

Nintendo should make more Joy con games.

Those reasons are so...meh. Splatoon did it, new console without many options and it's looking good.

I mean, I guess it could be the next hit, splatoon certainly proved many of us wrong. It'll be interesting how the game will perform.
