They might, but it is a Nintendo program and they would be giving out prizes and extras for non-Nintendo games. I think they would understand if 1st Party games were 50points and 3rd Party games were only 35. Atleast we still have an incentive to go out and buy those 3rd party games too.
If it were too much of an issue though, I did give another example of how to handle it with an extended Elite status marker if you include 3rd party games.
If you had nothing but 1st party games, it would still be 950 points
but if you also collect 3rd party games, you need a total of 1350points or something.
or maybe a Super Elite status where you need to achieve the 950points of 1st party like usual and a second meter that only tracks 3rd party points that goes up to 450points (you also get points for intend to buys and post play surveys too). You cross that line on both charts and you get Super Elite status and you get a super special prize at the end of the year.
If you only cross the Gold status on 1st party titles, but also cross the marker on 3rd party titles, then you get regular Elite status.
I actually like that 3rd way I came up with since it gives you 2 ways of getting to elite status and then rewards the most dedicated with a bonus on top of that with Super Elite status and prizes
