Ah, 2d is the way. 3d more often than not, feels like a rehash of other assets, personally. One DAZ model is very similar to many others, rare are the times they are distinct for me.
Still, it comes more to me being a sucker for a good and cute artwork
It really depends on the game tbh. I absolutely love 2D and especially pixel art games, but depending on the content and style, 3D can be really good too.
A nicely animated 2d game is greatly preferred to any 3d game. I find most of the 3dcg stuff borderline uncanny valley, so it helps a bit when the characters are far enough removed (eg 2d).
