It evolved from Siege to Earthrise to Kingdom (those three were all part of “War for Cybertron”) to Legacy (which started as Legacy Evolution and turned into Legacy United). I think now we are at Age of the Primes.Out of the loop with Transformers, aside from Studio Series. I got into Transformers with the Siege line, which became Earthrise and then I slacked off on collecting and lost track. Is that line still going and if so what is it called now?
I usually call it Mainline, but it has also been called Generations, which is kinda how it started off with CHUG (Classics, Henkei, Universe, Generations) which really refers to a particular scale which includes the size classes Deluxe, Voyager, Leader, Commander, and used to include Scout and Legends scale for really small figures. I find that Mainline is a good blanket term which can also include Studio Series, since they share the Deluxe, Voyager, Leader, Commander classes.Thanks! It's a confusing one for me because there isn't a forever running all-encompassing line name like we have with Marvel Legends or MOTU Origins and stuff like that. As far as Studio Series goes, I'm still debating about whether I want to upgrade my old Constructicons to the newer versions. They kinda look okay as is sitting on the shelf and that's a big price tag by the time they all come out.
