Partnering with Apple for exposure seems cool and a good move for Nintendo, but I am sure Apple was knocking on Nintendo's door first asking them if they could bring something nice to their press conference.
"Timed exclusive" is also 100% a thing where money exchanged hands, no reason to do this unless this is paid for. But Nintendo can sure get something out of announcing this at the Apple conference for themselves.
Also, if they bring out the Fire Emblem game out like that, and it has stickers for whatever this message thing is that I never used, I will seriously consider upgrading my iPad, not even joking.
Yeah, I just can't believe Nintendo took money for a exclusive OS rights for one of their IPs, it's crazy when you think about it.
and yeah the sticker thing definitely pushed me to get a iOS device too.
