A Call of Duty RTS? Only if they brought back WC3’s Heroes, and maybe gave you a whole Company of them to manage.
RTS’s need a massive new hit to redefine the genre. The starcraft style is stale and too slow for how most people game today. I’d kind of enjoy seeing people take another shot at where C&C4 and AoE3 were trying to go: something more tactically oriented with a greater emphasis on mobility. I think that era of RTS innovation got completely hamstrung by trying to force every game to not only have multi-player but also to be an esport and also to be a live-service endless money machine.
You may note that games today are still being ruined by the same forces.
Dawn of War 3 was absolutely ruined by them trying to make it an eSports. I find most RTS doesn’t give that same feel we got when WC3 first came out or later on when Company of Heroes was released. They were solid games that brought something new to the genre.
RTS’s need a massive new hit to redefine the genre
RTS is a very broad umbrella term. I would have thought a CoD RTS would be more along the lines of CoH in its design than WC3. Though I could see mixing the two to create a tactical RPG RTS.
Because of the broad category that is RTS, I don’t think it’s necessarily right to characterise it as the genre needing to “redefine the genre” or have enormous innovation. AoE4 is an excellent and very successful game, but it basically only has relatively minor refinements on long-lasting staples of the classic RTS genre. And AoE2 is still enormously successful despite being 25 years old this month (with the obvious remastered graphics, newer QoL features, and new patches and expansion content along the way).
I’m not sure I agree with the live-service complaints. Maybe there are some RTSes that went that way, but one that you mentioned was AoE3, and it certainly didn’t. It was buy-once, play forever. (There were 2 major expansions in the same vein as the expansions of earlier Age games with significant new chunks of content in each, but nothing live servicey.) So has been every one of the Definitive Editions (including Age of Mythology: Retold) and AoE4. They do put out new paid content on a regular basis, which is frankly necessary to be able to keep funding bugfixes, balance patches, and server costs. But nonetheless the content has been very well-received by the community, and is entirely optional and doesn’t lock you out of playing your old content at all if you choose not to buy it. I’m not involved in any other RTS games, so maybe they are doing more live service stuff. Shame, if so.
RTS may just be a niche genre. It doesn’t need to change to attract a wider audience, because doing that would be to change what attracts its current audience. And that’s ok. Not everything needs to be for everyone.
Not that there aren’t things that RTSes could do to try to maximise their audience. If the game is esport focused, a good investment in esport prize pools goes a long way, and so does making sure your game is in a high quality state before it gets released—even if that means delaying release. AoE4 is an excellent game today with a pretty solid playerbase, but it could have been in a much better state if it hadn’t turned away a large number of both pros and low-level competitive players by the terrible state of the game at release. I’m also really impressed by the work the Age franchise has done around console compatibility with their main games recently, but I think greater promotion of this fact (for example by sponsoring console & controller–only tournaments) would help in that arena. I’d also love to see a real classic RTS game developed for mobile, which is why I was initially really excited about Age of Empires: Mobile, until the leaks came out revealing that it’s yet another Chinese knock-off like the thousands of cheap mobile games that have come before…only this one tarnishes the brand not just by indirect association/ripping off its assets in ads, but because it’s officially allowed to use the Age of Empires brand. Mobile is never going to have the high level of competition we see on PC, but I think if they put the same level of love and care into a mobile game (designed from the ground-up to be a mobile RTS) that they put into the console ports of their core games, it could be a great experience while on the go, and possibly provide an easier entry point into the genre for some newer players.
What I don’t want to see is the kind of RTS innovation that leads to completely new genres. MOBAs are fine for what they are, but that’s what you get if you embrace the idea that RTS should completely innovate to capture audiences with wildly different tastes: an entirely different genre that no longer appeals to RTS fans.
