80

This is tough, I say it'll get an 85.

I feel like colorful new franchises that emphasize action over exploration or realistic graphics have a ceiling with gaming critics. These types of games are aimed at different audiences than the critics, who have other preferences, so they're very reluctant to give it near-perfect scores. Overwatch might be the exception that proves the rule.  When Splatoon was revealed I guessed its ceiling was 80, so when it landed on 81 I figured it was a game that everybody would love and still be playing or talking about years later. The sequel will probably score a mite higher now that everyone knows it's okay to like Splatoon.

As for ARMS, I think that ceiling is also 80, meaning that it would have to be really addictive fun for critics to go that high. So I'm going to guess 77 or 78, based on reactions to the punchfire.

That's definitely not easy to predict, 80 is the safest option.
