Also, at least in my opinion, the very limited nature of the total set of states relative to the total set of states in something like an RTS lends itself to repeat engagement and analysis. You can, and likely will, see exactly the same board position in more than one chess game. You almost never going to see exactly the same game state in multiple SC games. That changes the dynamics of post-game analysis and skill development, IMO.
(Don't get me wrong, I enjoy both- but I do enjoy them differently.)
True with 1 exception, 1/0 (all moves in 1 minute per side) bullet, some of the really strong players at that use high end/high accuracy gaming mice because with so little time even a slight decrease in move time pays off.
I don't play anything less than 15/15 or 20/10 though and your point holds for that.
This makes it reactive, rather than proactive. Reactive judgments are driven more by depth of knowledge, habit, and memorization. Whereas proactive judgments are driven more by predictive/entrepreneurial reasoning. Both seem equally driven by calculated risk with a little psychology involved.
Ancillary skills are important in start craft, I'll give you that. But at least in DotA those skills could be learned by anyone relatively quickly. I don't play video games any more so no other examples come to mind unfortunately.
I don't know, but it is very addictive. It's a 'fight to the death', but in a realm of ideas. There's a neverending amount to learn, so many different types of situation can arise in a game, so many varieties of strategy and tactics, unlimited, it seems.
I'm not sure what you mean 'these have all the same Dynamics plus some. They are so dynamic'. There is a fairly common chess variant, Chess960/Fischer Random, where the pieces are shuffled before starting, and you will rarely see the same opening move. But it hasn't taken over from normal chess, which seems the better game to most people. The opening move won't be new, but after a few moves you're in uncharted territory.
