According to a Reddit post (link) by user SuperGuff64, the upcoming Ubisoft turn based tactic game, Mario+Rabbids Kingdom Battle, will be running in the below specs:
TV mode: 900p, 30 fps
Handheld/Tabletop mode: 720p, 30fps
While the graphical specs for TV mode seem to be disappointing, considering that even games like Mario Kart 8 deluxe runs at 1080p 60fps, ultimately the games success or failure will fall on gameplay. After all, Mario-esque character design tend to look good even sub 1080p and frame-rate is not a huge concern when it comes to turn base tactic games.
Mario+Rabbids Kingdom Battle launches for the Nintendo Switch on 29 August 2017
