The reason this site is dying.

[Evil Yoshi Toes]

That said, MFGG's community now is not without its problems. MFGG has become a much friendlier place with a lot less petty drama, but it has also lost a lot of its focus on fangaming. Part of it is, like General said, because of Mario Maker being a more user-friendly way of creating something similar to a fangame and therefore satisfying a lot of people enough. Another part of it is because, like Vinny said, there is a huge anti-fangame wave going on in social media. This is probably what hurts the most. Youtubers and gaming articles are misinforming people by telling them that any and all fan games will likely be taken down, despite our site having existed peacefully for decades. You can try to explain to people that these games are taken down because they are remakes or because they are monetized and that there are thousands of Nintendo fan games that encounter no issues at all, but people don't care. They just want to fuss and if you get in the way of their fussing they get upset and don't listen. It's unfortunate and it has definitely hurt the fan game scene, but it's something we can't battle easily. There have been efforts made to inform people properly, especially by the MFGG Twitter, but that only goes so far and tends to only be spread among people already in the fan game community which doesn't really help us grow.

I feel that there is a pattern with Nintendo Lawsuits, I mean here's as many as I can think of.
-Mario Royale (shares gameplay concepts with SMM2)
-AM2R (remake of an existing game, remake is already being made by Nintendo)
-No Mario's Sky (I don't know why, similarities to SMB maybe)
-SMB64 (C64 port of SMB, is too similar because of this)
-Princess Adventure (Creator was selling physical copies)
-Pokémon Uranium (Possible, it's similarities to the main series combined with it's dark themes could be a bad image for the franchise)
-Other Pokémon fangame things (I'm not a Pokémon fan so I don't know why)

Overall you either have to be remaking a game, Nintendo is making something similar, you are making money indirectly off of it or you are just unlucky
The question now is how Mari0 hasn't been sued in its 8 YEAR HISTORY!!! I guess is that it never went off outside of being a novelty, while Mario Royale went viral.

Well Mario Royale used exact level design from SMB so it was essentially a remake with multiplayer elements.

Pokémon is handled separately from Nintendo's other franchises and they've been infamous for taking down a lot of fan projects. I can't say much about it though because I'm not a Pokémon fan either so I don't follow Pokémon fangames.
