Eclipse's scenes animations are not 3d, the game plays as a "2.5D" top view rpg, the scenes are 2D. The initial build from before it was reworked used 3d for everything, but it was not sustainable. As style, that's a matter of preference, Starmaker's style is not much more preferable, a lot of ppl likes and is waiting for Eclipse.
You can see the previews on the Arvus games discord's Eclipse channel pinned messages.
