Well, the number one big thing is character selection. It just so happens that my interests lay outside their super narrow focus of G1 Season 1-2. I was born in 83, and I hit proper toy-begging age when the Diaclone guys were a distant memory. So I've always been more into late G1/BW/G2. In other words, right outside their focus. I do applaude their BW MP efforts, I realized a couple of years prior to their release during a rewatch that the animation models.. actually kinda scare me, haha. I am so glad Generations went for more decent animal modes. T.T Also.. every damn one of them has a faker chest. Except Megs, and he's just too expensive.
