Most of everything can be modified to a certain extent on the right side of the screen. Spawn a pit fiend for example and you can alter his height and hitpoints. I wanted a tall one, obviously, because I'm childish. It's also possible to select multiple buildings of the same type at the same time and tweak their values collectively - tweaking the colour scheme and trimming, for example. This'll be particularly useful if you want to build up forests, actually. Baudoin talks of "speed trees". By changing their seed values you can spawn incredibly varied foliage, sprinkling them around with the left mouse button. One of the great things about a project like this, Baudoin confirmed, is that all the work that the artists do can be made available, even if it's not used in the main game - so in other words, they made too many trees. As well as numbers and variety, it's possible to make things a lot taller - there'll be elevation changes on externals this time.
