@JustAGuy Drawing a still life is generally considered much easier than drawing anime style, unless what you actually meant was life drawing or photorealism or something. Drawing a still life just means you sit there looking at an object or arrangement of objects and draw what you see. Drawing a still life is a typical beginner activity in drawing classes for both children and adults.
As far as drawing people goes (and worse, animating them), this is generally something a beginner cannot do well enough for a game. (Well, maybe if it was a game that used stick figures; there are some pretty good indie games out there that do this.) But between a realistic style of drawing humans and a stylized one like anime or western cartoons, there's little difference in the difficulty of drawing a convincing person. People are something viewers are instinctively very picky about because we are used to reading meaning from details of people's facial expressions, body language, clothing/hairstyle choice, and those little details that communicate ethnicity and health. On the other hand if you are drawing flowers you can get away with all sorts of things like putting tulip leaves on daffodils or putting trumpet lily flowers on calla lily stems or leaving the middle parts out of a flower entirely. A lot of people have never looked that closely at a flower, and if it happens to be a fantasy game you're allowed to make up your own flowers anyway. But even in a fantasy game the audience will object if you manage to give a character two left hands in some drawing, or if your female characters all look like they have male faces, etc.
That stuff about understanding realistic proportions being important as a foundation for using stylized proportions is true; there are shortcuts though, for an artist who has no interest in drawing realistic people.
