Please implement something to teach players how to play

[Shurrikhan]

You can't teach common sense, you either have it or you don't.

You can, unless you're working off some wonky definition by which teaching can only refer to explicit step-by-step instruction. (And even then, it can be taught. You'll just have probably killed any motivation to bother learning.)

In any less artificially confined sense of teaching, well, that's exactly how common sense becomes common.
