In the end I didn't get everything painted, but there was paint on the models, and that is what matters. I've made a short little YouTube video with some thoughts on the game and on my paint scheme going forward.
In short, it is a really tight game, with a solid community and "scene". The chaps who were teaching me were really nice and are keen to foster a larger community. In fact, I was so enthused by the game that I immediately arranged to teach my local wargaming opponent, Taff, how to play, and last Thursday evening we ran through a quick Mangled Metal game, with Taff taking command of Kommander Sorscha. His impression was positive, so that bodes well. I am hoping to get involved in the Milton Keynes Journeyman league when that begins in September with my Protectorate of Menoth stuff. Whilst I was initially attracted to Khador's Tzarist/Soviet aesthetic, I really like the Protectorate of Menoth playing style. so I think that for now I will continue to build upon those things which are already painted.
