"Barbie Super Model and the unreleased Barbie Great Adventure"
Yeah, all two of them, one of which was never officially released, as mentioned above.
Honestly, the main extent of my familiarity with any of this stuff comes from the OCRemix track "Plastic Goddess" by Children of the Monkey Machine. And that's the only reason I'm aware that the soundtrack for Barbie Super Model, some of which you can hear in the above SNES Drunk video, is actually pretty okay. (The SNES version, anyway, as I'm not as familiar with the Genesis or PC versions' soundtracks, though from what I little I heard of them when I skipped around in those two longplay videos there, those versions seem fairly similar.)
And yeah, same as with a "proper" game based on My Little Pony, I wouldn't be above playing a "proper" Barbie game, either, if such a thing ever existed. And by "proper," I mean "not a nigh worthless, cash-grab, piece of shit game pumped out on the cheap because 'little girls don't care about video games'" or whatever. Where are the games for Barbie and MLP with equivalent quality to Ghostbusters: The Video Game or South Park: The Stick of Truth or Strong Bad's Cool Game for Attractive People?
As for the Barbie movie, I'm not writing off the possibility that I may actually watch it someday, but I haven't seen it yet.
