...and once again, Aaron speaks truth to geekish:
I agree with a lot of that above. I'm attracted a great deal by the prospect of making something my own. I mean, I took a Batman figure (this was before "action figures"--and no, it was not Mego...it was a parachuting figure from REMCO) and removed the stickers and "ears" and repainted it as a character I thought I created. (Well, it was a mix between the Flash and the Fawcett version of Captain Marvel!)
I even went through the tedious process of inventing color schemes for my proposed (and unrealized and abandoned) Warhammer 40,000 Sisters of Battle/Inquisitor/ Knights' Guard army. If the pieces are unpainted, why paint them in a color scheme decided by others when you're perfectly capable of choosing on your own?
I missed out on the emergence of MMO flight sim warfare, and that's probably what I would have done if I had the hardware to support it. I'm sure if I could "do" Second Life or something like that, I'd still "build" planes and/or robots and/or starships.
Maybe it is "playing with dolls" for the 21st Century. Does that make creating a wallpaper for your computer "finger painting"? Does that make the meme idea "playing Post Office"? I for one can use the playtime.
