If you are fond of real-time strategy games, here are the best five to buy during the Steam Summer Sale 2025.

Real-time strategy games are a genre that features titles focused on strategic planning, resource management, and tactical combat. Unlike turn-based strategy games, everything that happens in RTS, including army maneuvering, production, and economic development, takes place at the same time, and players must make decisions on the go accordingly. The genre first gained recognition in the 90s, and has been going steadily ever since. Now is a great time for fans and newcomers to get some good RTS games since many great titles have a significant discount due to the Steam Summer Sale. Here are our top five picks for it.
