I’ve been thinking about this a lot, lately. I think cheat sheets should ideally be followed rather than learned. Like checklists, but more complex. If this happens, do this, then do this. One problem is that not all games are procedural: some of them are full of mechanical options which can be activated in very different situations, outside of any formal procedure. And this, in my opinion, is how a game easily becomes complex and stressful to learn. OTOH, a very procedural game can feel heavy and too rigid.
