Golf and Archery are also considered skill-oriented sports.

Yeah, there's a level of physical exertion. Olympic archers only use 50lb bows however. Its a level of strength pretty much anyone (even non-athletes) can reach. Gone are the days of 100lb or 150lb longbows (weapons of war half-a-millennium ago).

Golf requires you to walk 18-holes while smacking the ball every now and then. I do get tired from swinging the clubs (I'm out of practice, and those weird back / stomach muscles go tired unless you practice). Still, its considered a skill-sport rather than a strength sport.

I suppose that's fair enough. The peak and average exertion for curling is well above either of those, but it's clearly not the physical strength/endurance that determines winners. Perhaps an odd entry point for e-sports though, given examples like you have given.

I was not expecting it when I started, but I recall coming home sore from curling practice.
