I think a really good rule of thumb for too much juice is: pause the video at any frame and measure how long it takes for you to identify:
if you can’t tell all of these things almost instantaneously then the game is too juiced
for reference, here’s a screenshot from Doom (1993) (the good one). notice how your eyes are instantly drawn to the zombie shotgunners and imps, because they’re the most relevant things for you to be looking at. notice how quickly and easily you can identify everything that’s happening in this picture just from a glance
maybe I’m biased because I’ve played a fuckton of Doom (1993) (the good one) but I think that the visual style of Doom (1993) (the good one) is very visually appealing, very stylish, and most importantly very very clear at a glance
