I do. I've been with my boyfriend for nearly seven years now and so we share a lot of support for each others hobbies. For ponies, I collect versions of Princess Luna from FiM and he collects Trixie and has a fair number of offical ponies as well as a couple of customs. It was funny, once we were in ToysRUs and he thought a G3 was a fakie and said "whats wrong with this? It isn't Rainbow Dash's cutie mark...... I knew that. I have brain cells dedicated to that knowledge. I'm gonna go sit in the car now..."
That was his downfall right there. It is really nice though, having him interested when I'm working with a custom and having a buddy to go pony hunting with, and the fact that he has no problem with the earlier generations.
