Of course having some animations in a game is better, but if that makes the waiting time much longer and the anims ain't even that good then I'd rather have none or only for scenes that are important. Like a first penetration.
animated is nice, but not 100% necessary to me. most vn's i read use frames to make it appear they are moving. one that has really good animations though is Tribulations of a Mage by Talothral.
Depends on the Animations, sometimes they end up so stiff and lifeless that it distracts from the imagery rather than add to it.
While I do prefer animation, I rather it not just be put in because a dev thought it was necessary without the proper care to see its done correctly.
