I play minigames. I don't do minis. At all. I'm a fucking ham-fisted ogre when it comes to anything remotely involving art talent. This is why I love me some MegaMek.
Mistakes?
Screw liquid diamond. I want to be able to fling apartment building sized ingots of extracted metal into space.
I painted a mini once back in college. Spent days working on it, under the careful guidance of MamaCow (she paints ceramics, good stuff). It was awesome. Not perfect, but fucking awesome for a first try.
