Well most of it's active life has already been done on Switch/PC. No problem here to get some interested Xbox players into the party. Though it seems to me Square Enix received a good check from Microsoft to make the port happen. Also, this could mean the game might come to the PS4/PS5 sooner or later now.
Why do you think Microsoft put a check?
Glad more people can play it now. The same could happen with other SE Switch exclusives, like Bravely Default II (and the entire series, for that matter) and the future Triangle Strategy.
My bet with The_Liquid_Laser: I think the Switch won't surpass the PS2 as the best selling system of all time. If it does, I'll play a game of a list that The_Liquid_Laser will provide, I will have to play it for 50 hours or complete it, whatever comes first.
