Thank you guys. I want to say that I like modifying models more than I like painting them, but I'm not sure if that's true. I am really happy with how I ended up painting Telesto, so even though he is a totally unmodified model, it gives me great satisfaction to look at him. But what is definitely true is that I look forward to modifying a model more than I look forward to painting it. The conversion gives me ideas and thrill that painting doesn't, even though the conversion results aren't always stellar.
One thing I am unsure about right now is why I am still getting these models. What am I up to now, 65 models now or something? I've used no more than half of them in any of my games I'm sure.
I guess the answer is just that I'm more of a model collector than a gamer, and the modelling side is more my hobby than gaming will ever be (even though I love nerding out about rules). So getting new guys for the arena is less about having gaming pieces and more about just nurturing the collection, model train style.
Atrox, Gjallr and Gaius just arrived this afternoon. Definitely doing something to all of them.
