I just thought, "Hey, we're gunna be playing a game with Mechs and giant monsters, right? I wonder what everyone's favorite Mecha/Kaiju Anime or Cartoon is." If we're speaking strict Mecha, I think the Gundam series is on top of a lot of people's lists. As for me Gundam Wing is the Gundam series from my childhood I remember most fondly. As for Mecha vs. Kaiju, this might be a bit of an obscure pick but I have to give it to Betterman. I know Japanese animation has inspired a plethora of films/cartoons so I wouldn't mind hearing opinions about those as well. I particularly enjoyed the short-lived series Megas XLR and Symbionic Titan.
