Hi. The game is mostly 2D, but there are 3D elements, namely the colony view, the ship design screen, and the space combat. The colony view and ship design screens have 3D elements, but there aren't quick changes or camera angle changes, so it should be alright if you have motion sickness. The space combat is more dynamic, and there are some camera angle movements, when you finish off targets, but you can switch that off in the Game Settings ('Disable Zoom & Shoot' option). Apart from that, and while 3D, the combat unfolds without many quick motion changes, and no other camera angle changes apart from the 'Zoom & Shoot' option, that you can disable..
