KoDP has a strategy board in place with distinct entities with differing characteristics and goals vying for resources. If that's not a strategy game, I don't know what it is.
What resources you are vying for? There is only land, and you don't need much of it. In fact, you only need it when the game starts whining "hurr durr, you grew too big" - which happens shortly before "hurr durr, you grew even bigger, we don't like it, let's split the tribe and start again, awesome idea, huh?"
At best, you'll make a couple of tribes relocate elsewhere on the map, and that's the end of your expansion. And that, too, happens at random, lol.
