@Dova, I'm not making this into a zero sum game. I thought of other ways Yugioh could be played. It does not preclude the current game in any way. For instance, I thought of (somehow) hosting Forbidden Memories or Duelists of the Roses tournaments, but that doesn't mean I'll go demolish the card shop next door. I won't go Kim Jung Il (or Michael Pence - pick your poison) and make my Yugioh the only Yugioh in the world.
I'm "fixing" Yugioh for my fanfics. In these first writings, the meta in the fanfics matches the meta in real life. In Season One, the meta is like our meta in 2004-2008, hence all the Chaos Control, Monarchs, and DAD decks. In Season Two, the meta is like our meta in 2015-2016, hence all the Turbo Towers and Draco pendulum stuff. Season Three, the meta is like our meta in 2017-2018, with all the new link monsters. My main characters tend to use rogue decks, and you can't go rogue if there is no meta to go rogue against.
Only problem is the duels look terrible on the page and focus is taken away from conflict and character development. They would look better in animation or live action, because the format would be visual, meaning no word clutters, but the chances of that happening are almost zero. So I have to make some kind of compromise or make the fanfic meta more like the anime meta, but still somehow have it resemble real life meta. Welcome to my world.
Each individual idea completely breaks 90% of Yu-Gi-Oh, so you would have to get rid of most of the current gamestate. Less of Yu-Gi-Oh, more of an original card game that uses some cards.
I'm aware of that, hence my first paragraph. I notice Duel Links looks like it's revamping the game from the ground up. The developers are crafting Duel Links meta in a very careful way. To each his own, really.
Basically, you mention it in your original post, but you don't seem to say if you are actually doing it or not; do you want to remove a large portion of the current TCG card pool, or work around most of it?
I did say they were just thoughts I mulled over on a Saturday afternoon. I doubt I would put my ideas in action beyond my fanfics. If I did, I would just make different forms of Yugioh that would coexist together. I play whatever kind of Yugioh I want depending on my mood, like how I play a different installment of Mario Party whenever I feel like it.
People online tend to react very strongly to me online. I guess it's because I sound aggressive and radical when I don't mean to.
