How does the work of CS (Valve) developers differ from Civilization developers in terms of monetization?

Counter-Strike (Valve) developers work with a monetization model focused on microtransactions and in-game purchases such as skins, cases, and battle passes. This ensures a steady stream of income from an active player base, where purchases do not directly affect game balance (free-to-play with cosmetic enhancements).

In the case of Civilization, monetization is more often based on selling the game itself and expansions (DLC), as well as deluxe editions. This is a more traditional model — buying the product and its expansions, without ongoing microtransactions. This approach is aimed at long-term value and a deep gaming experience, rather than frequent in-game purchases.
