I don’t think I can stomach the plain YuGiOh simulators from back then. It’s quite boring, especially after having played the modern game. I do think it’s worth getting at a dicount for the weirder ones though.
However, I’d buy a collection of all their weird 3D games in heartbeat. Forgotten Memories, Kingdom of Illusion, Duelists of the Roses and so on.
I don’t think the mainline games will change anytime soon, just like they didn’t adopt the battle styles of the last Legends game.
Like, don’t get me wrong, I think the idea they are going for is good. But I also think it does look really clunky and would kill the PvP scene.
Personally, I’d go for a turn based and position based approach like Like a Dragon or Dragon Quest are experimenting with.
My vote goes to Dragon Quest. Early gaming was dominated by JRPGs like DQ, Final Fantasy or Chrono Trigger. Pretty much every modern game has RPG elements. While there are earlier RPGs, DQ popularized them and invented the JRPG.
Of course, literally speaking, the first game ever is the most influential - therefore Tennis for Two.
