[Master Belisarius]

I think that's 90% science and 10% art.

But think that some people learn fast (usually playing against a more experienced player), and other people, never will learn how to play although could play a lot of SE4 games...

In SE3 times, I have taught (yes, literary I have taught!), about my tactics and strategies near of 12 players. I could be a bad professor (admit), but only 2 or 3 became really good players.

Then, although I think that play SE4 is a science, also I believe that not everybody learn at the same speed. In my view, it makes the difference.
