While there have been a few real-time strategy games release for home consoles, the genre has mostly been limited to PC. This was once due to the technical limitations of consoles, but with current and next-gen consoles being as powerful as they are, this argument is no longer valid. However, there are some other reasons RTS games rarely release on home consoles.
Real-time strategy games used to be extremely popular. The genre began to take off in the mid-90s due the success of games like Command and Conquer and WarCraft. By the late-90s, RTS games were the next big thing in PC gaming. While developers created a few home console ports of popular RTS games, many were inferior to the original computer games. Interest in real-time strategy games started dwindling by the early to mid-2000s as gamers started shifting their attention to other genres. There are still tons of great RTS games with thousands of loyal fans, but they are not nearly as popular as they once were.
The rapid drop in popularity over such a short period of time could be a reason why so few RTS games are on home consoles. There were a handful on fifth generation consoles like the original PlayStation and Nintendo 64, but by the time the sixth-generation came along, they were few and far between. It simply wasn't worth the money and work to port these games for limited profit, especially as some started to see the RTS genre as a fad.
There's also the fact that console gamers tend to like fast-paced games rather than detailed, tedious strategy games. RTS games are extremely meticulous and take time to learn all the ins and out of, something PC gamers are often more willing to do. On the other hand, console gamers usually like less complicated games that don't take a lot of time to learn. Games like Grand Theft Auto V, Call of Duty and FIFA all do really well on consoles, and while they work great on PC, they aren't as popular as League of Legends and Dota 2 among computer gamers as a whole.
The fact that home consoles don't have a mouse is another contributing factor for the lack of RTS games these systems. Most of these games heavily rely on a mouse for their controls, so playing them on a regular controller doesn't feel natural. PlayStation 4 and Xbox One players can buy a mouse and keyboard, but there are very few games for those systems that play well on that kind of set up. Since RTS games are now somewhat of a niche genre and most are specifically made for mouse control, there isn't much of a reason to bring them to home consoles.
Finding good RTS games for home consoles can be difficult, as many are PC exclusives and simply don't translate well to other platforms. Playing strategy games without a computer mouse can be awkward, and the apparent lack of interest from console gamers provides little incentive to port them. Unless there is a newfound interest in the genre, it's safe to assume that RTS games will stick to PCs.
