Nintendo, while aggressively litigious, do so to maintain the value and exclusivity of their IP.
Their games also never go on sale, and all sell really well over time, unlike many releases from other publishers.
The result is that Nintendo are able to release a solid cadence of high quality, first party games free of other forms of aggressive monetisation, maintaining the value of the games as art.
I think you’re in the right neighbourhood with that opinion! Remember folks: upvote if you think it’s unpopular.
Also, they do have games on sale from time to time, but it’s never more than 33% if you’re lucky, and only a few select titles. You’re better off buying second hand. No money to Nintendo and cheaper for you.
