I personally collect just ONE version of figures, unless I'm crewbuilding, I'm nearly exclusive to deluxes and voyagers, and combiners (Primus/Unicron not withstanding) I just don't feel the need to have four Optimus Primes or 4 megatrons etc. I see MANY people collect MANY versions of one character, or ALL versions of every character. I'm just curious, what drives your collection? I mix lines I have prime with classics etc. Like my Prime figures are right next to my classics figures. And my customs are mixed in as well as I have two window sills, one for my bots and one for my cons. So, your turn? And why?
