I spotted that Privateer Press are planning on releasing some absolutely massive warmachines called Colossals:
I must admit they got me thinking that they got me thinking that Warmachine has some really interesting models and that I could even be tempted to have a bash at collecting a force. This mad thought lasted until I saw just how expensive the models all are! Even the regular infantry are really rather pricey!
With the size of the beasts they could even do with going for 15mm scale!
All the best!
