This is not me trying to be contrary or to challenge GC's wonderful enthusiasm or even to denigrate Strelets, but because I think the "fun" has never been missing - at least for me.
It's a hobby so by definition it is fun. The various plastic & metal manufacturers over the decades of my interest in the hobby, have produced figures that overwhelmingly added to my enjoyment. And, as figures last forever (I hope....) that's "fun" that's never gone away.
I freely admit Strelets are currently the best manufacturer of 1/72 figures. Their past performance also delighted me. As did HaT, Zvesda, Caesar et al.
So kudos to Strelets. And to all the others as well.So I say the "fun" isn't back. It never went away.
