Well... I don't want people sending in a bunch of low-quality maps just to be the one that hits that milestone.
A few years ago, I offered to old and new mappers that anyone who had submitted like 20 or 50 maps or whatever could get a free "Nintendo Quest DVD" from me (as I had so many after doing an event in 2015 but now needed to move them as they weren't selling). And, perhaps because DVDs are passé, or that a different version of "Nintendo Quest" is now on YouTube or whatever, very, very few people actually took that deal.
But it was around the time that this one person, a new mapper, who probably only just wanted the "free" DVD, started submitting a lot of low-quality stuff. I'm not one to refuse maps if technically they are maps, but man... is the site always improved with more maps, especially if they're like those?
And as nice as it is to be able to say we have lots of maps, technically maps would work better the fewer there are. As in, no unnecessary fragmentation.
Before we got complete Super Metroid maps for each area (thanks, Rick Bruns!), someone tried to send in maps they had extracted from the game somehow... meaning that it was hundreds of images, separate files, one for each room. Come on, a single room isn't really a map...
I want there to be 50,000 maps, sure, but we'll get there. And if I say we're close, I hope that if anything, that it encourages people to continue to make good maps, not to pivot to making worse maps that they can pump out faster.
