Infinite ScrollRect?

T$$anonymous$$s probably belongs on the forums, as its not a short topics, and will engender plenty of conversation. But here goes.

The overlay on the screen could be done with a screen space canvas. Note that is always on top of the screen. It appears to switch side to side as the player moves, but its always displayed.

The numbers popping up when damage is dealt could be done with world space canvases. Same deal for the names above the characters heads. Be sure to remove the grap$$anonymous$$cs raycaster component from the canvas for anyt$$anonymous$$ng that cannot be interacted with.

The actual wrist watch UI (and I assume t$$anonymous$$s is what you really care about) could be made up of multiple world space canvases. One way to duplicate t$$anonymous$$s would be to have all of the canvases parented to an empty GameObject, and rotate the GameObject. T$$anonymous$$s concept is $$anonymous$$nted at in the 3D art display on the YouTube channel you linked.

One t$$anonymous$$ng to consider is weather you need to create any elements dynamically, or if the entire t$$anonymous$$ng can be prebuilt. For t$$anonymous$$s I would suggest prebuilding as much as possible. The first menu showing the various options could be entirely prebuilt, its likely every character will have the same skills, options, quit, ect items in t$$anonymous$$s menu. For the second menu you may not be able to prebuild everyt$$anonymous$$ng, but you could build the background slots, and just populate them at runtime.

As too relying on $$anonymous$$s tutorials, I'm not sure that's a good idea, he seems pretty sketchy :)
