Have you tried the various Firefox forks? If one of your primary problems with Firefox is a belief that they are “evil like Google” then switching to a browser developed by Google and further entrenching their monopoly on the market is a very strange decision.
Nintendo has a few things going for it that other developers don’t, like its relatively long and consistent history and the fact it has sort of transcended video gaming to become a general pop culture icon. It also consistently releases bangers and the occasional flops are usually “creative but flawed” rather than just outright broken or boring. It doesn’t chase market trends to the same degree as its competitors, which gives its games a more timeless appeal. All those factors add up to give Nintendo games more long-term value, either as collector’s items or simply as fun video games.
