I'm sort of curious if it would be almost a boon.
My thoughts: Because E.A so rarely puts their games on Nintendo systems, they aren't really in a conversation as to what makes the platform attractive. E.A's lack of Nintendo is also a common criticism of the platform, as it is a fairly solid hole in their lineup.
However, should E.A games become locked on a single platform, Nintendo not having E.A games is basically the same effect as saying Nintendo sucks 'because it doesn't get Sock Boy and Sea of Thieves'. So you won't really hear it anymore.
Of course I am aware of the argument that Microsoft would have E.A be like Minecraft and appear on multiple platforms, but given how much of a 'buy a console' the sports titles are Microsoft may have more reason to hold them to their own self instead of giving them to Playstation.
The Democratic Nintendo fan....is that a paradox? I'm fond of one of the more conservative companies in the industry, but I vote Liberally and view myself that way 90% of the time?
