It's not just that.. maybe I'm just not sentimental or whatever but even when I was a young kid, I was always disappointed in the chunkies... how I couldn't transform it into GERWALK the way I saw it done in the cartoon, how inaccurate the sculpt was, how it had such limited posability, I was plainly aware of the flaws. I loved it because there wasn't anything better and I longed for something that really captured the look and the features of what I saw on TV.
For me, the 1/48 and now the 1/60 scale toys are those hopes and dreams realized and that's why, even though I'm an old crotchety bastard who grew up with chunkies, I'm more than happy to leave them where they bring me the most joy, in the warm glossy idealization of my memories.
