Thanks for the replies so far. I took a look at the game in a shop in Surbiton Heroes and Legends and ended up with the rulebook, one fate deck and the Perdita box to get me started and to look through the rules.
I am never going to be a competitive player but i liked the models, and play schematics so will try a relatively simple style game with my 9 year son for now - he seems quite keen and ill probably help play both sides for a while.
Anyway got a bit taken with the terraclips and bought a Streets set - looks great all set up and was fun to build too. My son has already adopted it with some of this other game models.
Will try and post a pic on my website soon - but the next step is what is Perdita's opponent going to be. I was orginally tempted by Rasputina (liked the models but not sure about spell orientation given its v my son).
Theme wise with the Malfaux street the Guild Guards would work so well as the idea of street defenders but no idea how they play. Other choice is probably the Victorias as again the models are great and i think may work well v Perdita in a melee v shooters style game.
Thanks for any thoughts again.
