Well the title says it already, so why did you start Warmachine or Hordes or both maybe?
For me everything starter actually with Confrontation. Well everything started actually with me not having so much time anymore. So I was looking to downscale. At first I started playing Warhammer Skirmish games and made some house rules for 40K skirmish games. But I played less and less games. By accidant I discovered Confrontation and started collecting the Wolfen (just for painting reasons, as I'm also a Werewolf fan) for they where kinda unique. Shortly after that I got pissed by GW politics (I really don't want to go any further in there, as I really don't intend this to become a flamewar) and decided not only to collect Rackham Miniatures, but to play them too and switch to Confrontation. My Girlfriend (big dwarf player) didn't like the Rackham Dwarves and she also had some trouble to decide which Confro Army to take. I saw though, that she really liked the Wolven, so I gave her the Wolven and started collecting the Orcs myself.
Since then we are enjoying Confrontation a lot and play it quite often now.
Well, surfing the web (and warseer of course ) I heard more and more about this Warmachine, but really never looked into it. Once in an indie store in Germany, I saw Warmachine minies and though, hmm not really in the mood for a Sci-Fi game (I still prefer Fantasy even though I played 40K too). Yeah, shame on me, I really thought that Warmachine was something like 40K.
Finally at some stage after seeing that there is a seperate PP Forum I decided to investigate this a bit further. And then I saw it. It's Fantasy after all and it has Steam Machines in it. I absolutly love Steam Tech in Fantasy games, as it gives you so many opportunities for building scenery and making scenarios (big D'OH on me not noticing this before). And not only this, when I moved to Dublin from Germany, I was really annoyed that there was no shop to buy Rackham Miniatures from. And while surfing the PP site, I saw they named a shop in Dublin selling Warmachine and Hordes.
I went to that shop and bought me both books (Warmachine and Hordes) and to my joy, they sell Rackham minis too.
Reading to see if I would like the background I must say I really like it alot and I simply love the Trollbloods. I play Warmachine too of course (steam powered Warjacks, yaj ).
My GF is not much a fan of Steam Tech. Still she likes a few miniatures, but not any Faction in Warmachine or Hordes to collect them. Doesn't matter, because I like to collect several Factions usually. I already bought several starting boxes for Hordes and Warmachine and started to play Warmachine and Hordes with my GF and we both like it very much. Now my GF plans to buy a few minis on her own and wants to paint a few too (she's sooooooooooooooooooooooooooooooooooo much better then me, actually she's really good at painting).
So what was it in the end that brought me to Warmachine&Hordes. The Scenario for sure (and the Trollbloods), but also the minis, while not all of them look great, they have this great poses like Rackham Minis and are not that stiff like so many GW minis are.
