My interest faded with reduced articulation and hard to find releases and no new characters. Honestly the same would happen to some degree with realistic if all those things happened.
Think about that a minute though... besides the articulation, that's sort of happened.
Fan-interest in 3.75" is at an all-time low I think too though... It's hurting all over.
I don't know on some of those vehicles. "Big" vehicles kicked off with the Falcon and At-TE... The show may or may not have helped one of those. I think that's a matter of some debate. Some of your vehicle choices, again I think that's of some debate... I think the Swamp Speeder would've happened, and so on. The V-19 I don't think would've necessarilly been looked at thoroughly without the toon though. I think they needed a small affordable Clone Fighter and that fit the bill at the time. I could go either way there I think. Droid Gunship, I don't know... I think the tank droid would've happened.
The Republic Fighter tank is a tough call. It's from a video game actually, and had nothing to do with the toon... Again was it that they needed a Clone tank? or did they just want something new that they hoped everyone would appreciate? I don't know there.
I DO think the giant tri-droid might not have happened without the whole Cristophsis pimping of it though and it's to this day a glorious piece of armor.
I think a lot of the Class I stuff though, no way it'd be out without Clone Wars for inspiration more than realistic stuff. And the nice new AT-RT I think wouldn't exist either. Far superior, to me, than the battery operated ones which I actually kinda liked.
I agree on the Turbo Tank, but then again I thought it sucked too at the time.
I think the big ships kind of needed Clone wars, but then again nobody supports the big ships either. I rarely see people pay full price including the MTT this year, the shuttle last year for sure, the AT-AT, etc. Maybe thanks should go to kids instead then.
What's funny in all this is often times people should just thank kids because kids got them some of this goofier junk. Kids who buy the Ani's/Obi's... Hate the business model but the rehashed recarded junk funds the obscurity. Hasbro's laid that out plain over the years.
