Wow I feel like the outlier... I have played with my ponies recently!
Well how I play with them now is different to how I used to play with toys (I couldnt own a MLP when I was younger... yay for being 17 at having my first pony P
Rather than making my regular monarchy or slice-of-life themed charade like I did with my teddies and whatnot, I use my ponies in play (twice now) as a sort of puppeteering thing... I'd voice as them and make them talk, but thats only been when I was actually handling them (brushing hair etc)... its fun! =P
