simplistic? have you looked at the screenshots?
The detail on the units is actually quite high. Look at the one where you can see the Naval units close up.
thats not low detail there.

And i disagree that the toy combat is the idea of the game.
Beeing a huge Dragon is definitly a completeley different notion.
A well executed steampunk look does not resemble toys at all.

Its all about getting reference points for hight.
And there are two ways of doing this: having overly large things or things that we recognize. Such as humans.
