What do you mean a "stronger" Nintendo presence? The top ten is -exclusively- Nintendo, and quite nearly half of the top 100 are Nintendo first party. The only way it could have a stronger Nintendo presence at this point is if games were docked points for not appearing on a Nintendo platform.
Indeed, there are already lots of Nintendo games on the list and that's because Nintendo games get lots of votes. If there was a bonus applied to games that get a lot of votes, it would favor Nintendo games because they are already the most voted for games to begin with.
