You're right, you know - the more "idiot friendly" a game is, the less depth it has. Tremulous has depth
That's just a cheap way of making the learning curve sound good. -.-
I think it's helpful to distinguish between
breadth and
depth. A broad but shallow game is one that has many different things to learn and to do, but not very much strategy in using any of them. Likewise, a game with a small set of simple, easy to understand rules can have
extraordinarily nuanced strategy. Neither is necessarily better, but I think it shows that there is no correlation between how easy a game is to
start playing and how long one can
keep playing it before learning everything there is to know.
