The person who emailed him the question is probably someone who made a CE thread in the past. :D
He doesn't have much experience with the game... but he's pre-judging, he still agrees it's free to play. He thinks that not progressing much in the first two hours (on mist) is bad. He might look at the game at some point because he feels that the energy system is innovative.
Starts at around 11 minutes.

I'll wait until he actually plays the game.
