>>1330because it's so much faster to make. You can have 5 cg artists animating a show instead of 50 animators hand drawing each frame one by one. 3dcg can look good, see gantz, houseki no kuni, hoshi no umi no amuri etc, but the main thing i like about it is that it allows super low budget weird experimental shit to get made that wouldn't have the budget or manpower to exist, for example tesagure bukatsumono and gdgd fairies. It doesn't look that great but it's funny enough to carry itself.
