Hello all! I'm a primarily G4 collector who has recently been getting in to earlier generations of pony as a result of thrifting and a wish to recreate the first ponies I first met (and was sadly not fond of at the time), the G2 Mc Donald Toys. My vintage pony collection actually started as an outgrowth of finding a G3 Minty & a G1 Anniversary Reissue Snuzzles. After that, I acquired most of the G2 McDonalds toys of my youth, picking up Sundancer (MIP, I'm actually looking to swap a spare thrifted Ivy for an unbagged version as well) and an Ivy, and later tracking down a Light Heart to complete (I think?) the set. Ever since then, I've collected all vintage of pony, though I'll admit outside of G4, G2 is probably my favorite.
As for G4, I've got a few brushables, and blind bag scale figures on the true pony end of the spectrum. Then, I have a small army of EQG minis, and almost the entire Seapony\Hippogriff collection, (I the reimagined Seaponies almost as much as I love the G1 originals song). I've got a few plushies, notably a large Luna, a Trixie (who spent far too long on a TRU shelf and had to be rescued), and a exclusive Night Stitch bat pony.
My dad also collects, we actually got into pony around same time back in 2012-2013 or so. He's on here somewhere, username is OleGrayMane or some variation thereof, same as on FiMFiction.
