For the Switch, folks should look for 3rd party exclusives. That was an under rated gem about the Wii.
The trouble with this is, SW doesn't really have the kind of 3rd party exclusives that Wii had. Not the quantity by a long shot and also not the types of games.
It has ports of some 3rd party games but we just had some data that something like 85% of the total game sales come from Nintendo's own games. And ports just aren't anywhere near as interesting as exclusives built from the ground up for the system would be, imo.
