I've found my MP collection changing over the years, at first I was a completist but have realised it's all getting a bit silly with the variant releases.
I have sold some off like my three clear packaged Hasbro Jets, I think I had 16 jets at one stage and still hadn't snagged the Takara Sunstorm.
Some I've kept because they look cool like Loud Pedal, but I got rid of Grapple because the character doesn't do much for me, but I have Artfire and Inferno which are similar looking mould-wise.
So yeah, I'm a bit all over the place, I'm glad Has/Tak are doing reissues and slight variants though, it keep prices down, yes we may lose on re-sale here and there but if it brings more collectors in and we can buy for our kids without stressing out about the item getting damaged with play that's a good thing.
