@Hawkshield - we're in early days, hermano. So far, they've just done Myr and the human race. Once all those basic mechanics are where they need to be, the other planets and races will be added.
I'm using these tests as a way to make all the PC building blunders I don't want to make with my 'real' toon once the launch happens. The skills tree is a new mechanic for me, and I've already made some dumb mistakes. Luckily, those toons wipe when the test ends.
