"Mirrors"

Well, a replay is positioned as a template for developing skills. You play yourself, then you watch how an opponent played the same scenario. If they did better, you remember what they did and try to repeat it in the next games. It's also useful to try to analyze and improve the game of a more skilled opponent, find their mistakes and inaccuracies, and play the scenario better than them, even if it's offline. In other words, post-game offline analysis of scenarios and player actions is just as interesting a part of the game as the online part, and it's much more useful for improving your skills. This approach will lead to success much faster than simply gambling on scenarios.
