I flicked between G1 and G2, and ultimately landed on G2. In reality, *my* G1 is Euro G1. Turbomasters forever!
I got into them because I had friends that had older brothers and they were amazing toys. The first toys I got were the gold box / cardback reissues, and then the Euro G1 releases.
I think I was in Year 4 / Year 5 by the time BW was out. Pulled away during Beast Machines, but was pulled back in by the first RID line when I saw Ultra Magnus - and I instantly wanted him, because I had always wanted one as a kid.
