I will, in the future. I've got...way too much Robotech stuff and even more on the way. I'm not in love with the rules yet, but I haven't played them out myself - just read them and watched some games.
So yes, in the next three years or so, at some point I'll begin the lengthy process of painting up figures and get properly stuck in. The figures have made excellent Battletech mechs (my only use of them thus far).
