I got a simple question I feel. How big of a learning curve is Phost from Thost, this is my first Phost game.

I'm played Tim host enough to know most the ins and outs, and I'm excited to give Phost a try, mostly because I've read the races are more evenly matched then in the old Tim host ship lists, which in some cases were borderline rock, paper, scissors.
