Notoriously hard and not exactly beginner-friendly, these 4X strategy games are perfect for players looking to challenge themselves.

Furthermore, due to its complexities, a 4X game can also last for hours, which also indirectly accommodates any PvP multiplayer experience, as it allows the earlier defeated player to quit the game first without waiting for the game to end for everyone. Although there might be additional rulesets needed for certain games, 4X games can still become the go-to for any exciting PvP experience.

Despite its very advanced age for a game, Sid Meier's Alpha Centauri remains a classic among all enthusiasts of 4X genre fans, as the game is regarded to be one of the very best in the genre.

However, the ancient netcode of the multiplayer still utilizes DirectPlay, which could become an obstacle for enthusiastic players who wish to experience the game in a multiplayer setting.
