This is not really a or question! (I have played somewhere in the thousands of avns) You can have a plot with a shit graphics or graphics with shit plot, but what you really need is both. So, games get away with having a slow burn, but you need a good plot for that; most of those crash and burn before you even get the first sex scene. if your making an AVN, you need a mix of 50/50, 60/40, or 40/60. You can push it into 70/30 with a good plot, but you need animations. The old single-frame javn's style is dead. Most popular avns have them for a reason, which is the standard now.
