It is not a game for casual players because either a) Depending is :-) or b) quenching the complexities of the game.
There are departures of course. Some examples are Ki, repetitive arenas or the but unfortunately often boring dialogues zuoft.
In short, if you like planning, collecting and especially end time you're right in the title.
Casual gamers but should keep their hands off of it ... unless you want to start to play more :-)
