^You don’t have to put it on spoiler. Everybody knows that Origin is a remake of MSG.
And what do you mean by Origin will use the the same 3D graphic engine as Unicorn?
If you mean that they’ll use the 3D CG for some Mobile Suits in static shots, then it’s possible. But I don’t think they will use a lot since 2D mecha animation is still Gundam franchise’s trademarks (except for all-CG project like MS Igloo).
And Sunrise running out of ideas is clear-as-day when they made that abominable AGE.
