Here's some gamedev advice for prototyping or the early stages of dev. I think this is especially useful for newer devs bc in those days it's really easy to get a kind of tunnel vision on anything. In short: skip as much default parts of your game as possible. I'll explain... When you're making a game, unless it is wildly original in every way there's usually two buckets of stuff: the original stuff, and the genre stuff. The original stuff is going to be what sells your game, and the genre stuff needs to be there to frame it all. It's what's expected.

A general (huuuuge) misconception on gamedev releases is that time between releases equals time of development. ie, if your fav game releases content every 6 weeks, that new content took 6 weeks to develop. This is extremely, very false. In reality, the content that just dropped may have been started over a year ago. And other teams within the company are developing things that will release later still. Inevitably, things change, get switched around, and there are last minute changes.
