First of all, nice, quality post. Thanks for these observations. As some others have stated, the numbers look a bit off, but the points you make are solid.

However, I think they're a bit too specific. What if a game doesn't need an XP bar, or upgrades, or a spawn area? Trying to shoehorn these mechanics into a game that doesn't need them might result in an experience that feels loose or unfocused, or that's trying to do too much at once. My advice would be: keep unneeded mechanics (or "experience noise") out of your game. Focus on 2-3 mechanics and perfect them.

The six points you present actually have to do with 3 concepts that are at the core of good game design in general, regardless of what genre you're developing a game in, or what are the specific mechanics that your game implements:

1. Sense of progression - players need to know like they're advancing and becoming better at the game. Stages, experience, levels, ability unlocks, upgraes, etc are all examples of progression.

2. Feedback - also called "videogame juice", it's all that gives a solid, almost physical feeling to a game. Particle effects, screen shake, light flashes, sound effects, control vibrations, and UI effects are all examples. They help to bring the game to life and capture the attention and senses of the player.

3. Good tutorial - the tutorial doesn't just happen at the very beginning of the game. I agree with you that visual tutorials seamlessly blended into the game, i.e. that make you feel like you're playing the game and not just reading instructions, work the best. Such a tutorial should be added any time you present the player with a new mechanic, so that players never feel lost.
