In a singleplayer game, currently, you can set which races or AI players to play against and which level of difficulty (Easy, Medium, and Hard). However, there's no real explanation of what these difficulty levels actually represent. Level of economy, agressiveness, build speed, etc... I'm assuming the release version will most likely define these better.

But in terms of setting up our singleplayer (and multiplayer I suppose, altho I don't play multi-player) games, what's the level of configurability? For example, setting up a custom game in Galactic Civ 2, the player has control of and can set almost every level and attribute of their opponents. Granted, SINS probably doesn't have all of the features of GC2, but should still offer a great deal of settings and options for the games, no? What can we expect?
