At first I was just like "oh, cool, I've got 3 of the 5 main suits from Gundam wing, might as well get the whole gang" but that's only recently.
back when I started building the models I watched some of Gundam wing because it had an english dub. Me, already being a gundam/gunpla addict, of course wanted the main 5 gundams in model form...
but I didn't even get my first of the main 5 until late last year, and it wasn't even 1/144 scale. I got my first in 1/144 a week or so after that.
THEN this year I got two more of the main group, which made me realize I could complete the whole gang by only getting two more kits (not counting the tallgeese)
So, skipping to present day, I have 4/5 main Gundams + the tallgeese which is the antagonist mobile suit.
Putting them in order by when I built them I have
HG Gundam Heavyarms
HG Shenlong Gundam
HG Gundam Sandrock
RG Tallgeese (custom TV version)
RG wing Gundam
So the final kit I need to complete my 1/144 Gundam wing collection is the HG Gundam Deathscythe
